->''"The softest thing in the world dashes against and overcomes the hardest; that which has no [substantial] existence enters where there is no crevice."''
-->-- '''[[Creator/{{Laozi}} Lao-tzu]]''', ''Tao Te Ching''

Razor floss is when any long, thin material -- string, thread, fine wire, etc -- is used as a weapon with AbsurdCuttingPower. Odd as it may sound, strings can become deadly weapons in the [[ImprobableWeaponUser right hands]]. Besides restraining enemies and even [[PeoplePuppets controlling other people's bodies against their will]], or triggering traps, they can be pretty handy for cutting. In many works of fiction, one skilled enough can use strings to cut opponents or even boulders, without hurting themselves. Naturally, monsters of the humanoid arachnid variety can usually be counted on to be using this trope.

Fantasy settings generally have this type of string made of human hair, while in more modern ones it's probably [[SharpenedToASingleAtom monomolecular]] wire. In series less reliant on the RuleOfCool, the wire usually manifests as garrotes or tripwires, with varyingly messy outcomes.

What the audience sees usually amounts to SwordLines sans the sword. Can be counted on to inflict an absurdly CleanCut on its victims.

In reality, cables and metal wires ''can'' be used to inflict not so clean but still pretty nasty wounds, provided they are of the right material and/or sufficient force is applied. Cheese slicers frequently use thin metal wires stretched in a metal frame to accomplish this trope, for instance. The monomolecular form is an eternal dream of materials engineering: any material with enough tensile strength to be used as razor floss could be woven into cables of the sort needed to build a SpaceElevator. [[note]]Carbon nanotubes could fit the bill if some hitches can be solved: production defects involving single atoms out of place can [[{{Pun}} cut]] their strength by up to 85%[[/note]]

A rarely addressed aspect of the trope occurs when the razor floss breaks or is cut. In such situations it may [[HoistByHisOwnPetard snap back at the user like a rubber band]].

Compare WhipSword and KillerYoyo. Subtrope of AbsurdCuttingPower.



[[folder:Anime and Manga]]
* The Disaster Armor from ''LightNovel/AccelWorld'' had this as one of the powers it could grant it's bewitched user. Used to horrifying effect with the Seventh Chrome Disaster attacks Yellow Radio's hunting party and apparently can pull players right to him before devouring them, as well as being able to change his trajectory mid-jump. This proves to be his undoing when he attaches the filaments to the far more maneuvable Silver Crow, who uses their unbreakable nature to slam Chrome Disaster into a building and weaken him enough to defeat him.
** A similar trick is used by the villainous character Rust Jigsaw, who can set near invisible jigsaw blade traps in the air around him. His preference for hunting close quarter or melee Burst Linkers made him a dangerous threat when they inevitably tried to get close to him to deal some damage. Again, this strategy proved bad when he face a Disaster Armor controlled Silver Crow, who cut the distance between them by applying his own wires to Rust Jigsaw and yanking.
* In ''LightNovel/ACertainMagicalIndex'', Kaori Kanzaki uses this to simulate super fast sword strikes. Her old student Itsuwa can do it too, but she's not as skilled.
* ''Anime/AfterWarGundamX'' has a [[MonsterOfTheWeek Mecha Of The Week]] named Britova whose weaponry includes a rocket-guided razor wire. The universe's backstory also has a Gundam Belphagor (no relation to the above) which uses several wrist-mounted wires to defend against AttackDrone-type weapons.
* Lubbock's Imperial Arms makes use of this trope in ''Manga/AkameGaKill''. He can also create a spear out of it, and use it defensively as a form of improvised armor to help him battle his enemies.
* The first ''Manga/{{Appleseed}}'' movie had a pair of gynoids with cutting whips that did quite a number on Hitomi's car and later on Briareos' HandCannon as well.
* Alice Fuji from ''{{Manga/Arachnid}}'' has Kumoito, a blade attached to special spider thread on a pistol that when shot flies on command and spreads webs for detecting and capturing enemies. She pulls a good number of absurd CrazyPrepared stunts with it through the series, culminating with stabbing a sharpshooter standing miles away from her.
* Yashamaru of ''Manga/{{Basilisk}}'' uses razor wire.
* One character in ''Manga/{{Bastard}}!!'' has this as a main weapon.
* The main weapon of Elf and Zwolf in ''[[Manga/{{Gunnm}} Battle Angel Alita: Last Order]]''. They've used it for defensive traps, deadly "cat's cradle" attacks, helping with Sechs' {{fastball special}} and... [[ArsonMurderAndJaywalking knitting a scarf supersonically in the middle of a tournament]].
* Jenos Hazard from ''Manga/BlackCat'' has a glove with lines of Razor Floss attached to the tips of the fingers as his primary weapon.
** Keep in mind, he belongs to an assassin organization whose members all have weapons tailor-made to their abilities, made of an indestructible metal alloy.
* The titular character of the ''LightNovel/BoogiepopSeries'' wields this quite efficiently and lethally.
* Linna Yamazaki from ''Anime/BubblegumCrisis'' has microfilament hair ribbons from her [[PoweredArmor Hardsuit]]'s helmet that can cut through enemies and weapons.
* One episode of ''Manga/CardcaptorSakura'' had Eriol manipulate Shaoran like a puppet using well-placed strings, much to Shaoran's horror. This is also stopped with Sakura using the Sword card.
* Showed up once in the manga version of ''Manga/CityHunter'', when Ryo had to deal with a killer dosed with [[PsychoSerum Angel Dust]]: due the drug the killer stood back up after getting shot ''three times'' with a ''[[HandCannon Colt Python .357 Magnum]]'', at which point Ryo pulled out a wire and beheaded him.
* {{Bishonen}} Benten from ''Anime/CyberCityOedo808'' used this as his weapon of choice, slicing through bad guys quite stylishly.
* In an episode of ''Manga/DescendantsOfDarkness'', [[spoiler:Muraki uses this against Hisoka]]. Not only that, but [[spoiler:he ties up Hisoka to a wall with razor so, if he tried to free himself, he'd get cut.]] YEOWCH.
* Razor Floss is one of Amagumo/Rain Spider's many, many weapons in ''Manga/DesertPunk''. He even compares it to a spider's web.
* A frequent murder weapon in ''Manga/DetectiveConan'' -- in fact, the first case solved involved a ''beheading'' on a roller coaster using a wire.
* L.A. from ''Anime/ElCazadorDeLaBruja'' is freakishly efficient with this weapon.
-->'''A random cop''': Get forensics down here ASAP. Uh, someone who's good at puzzles...
* Marco Adriano from ''[[Manga/{{Gangsta}} GANGSTA.]]'' uses impossibly long garotte wires that he stores in his specialised watch. With them, he's able to [[CleanCut cleanly slice through]] flesh and bone with seemingly little effort.
* Kazuki from ''Manga/GetBackers'', who's also known as "Kazuki of the Strings." They're just ordinary koto strings (harp strings in the Tokyopop version) that defy the laws of physics because of the [[{{Vibroweapon}} vibrations he applies to them with his fingers]]. The picture above is actually a relatively tame example; in the last arc of the story, he destroys multiple skyscrapers in seconds with his strings. Other characters who use strings can also create perfect body-doubles of themselves, tigers, and supernatural cocoons attached to the heart.
* A brief murder mystery in ''LightNovel/{{Gosick}}'' involved a motorcyclist who was beheaded by a strand of wire stretched across the road.
* Triela makes use of one of these to strangle a guard in an episode of ''Manga/GunslingerGirl''.
* Surprisingly enough, this appears in ''Manga/HaruhiChan''. Yuki uses it to [[ItMakesSenseInContext restraint a mutant Santa Claus]].
* [[CoolOldGuy Walter C. Dornez]] (pictured above) of ''Anime/{{Hellsing}}'' is a prominent example. With ten monomolecular filament wires, he can obliterate armies of the undead. [[spoiler:After his FaceHeelTurn,]] he can slice ''buildings'' to pieces and mesh his wires into barricades. He also takes up [[PeoplePuppets puppetry.]] As sharp as they are, they can also be surprisingly prehensile and delicate when he wants them to be; for example, he used them to grab a pack of cigs when he was 14. Also, he used it to grab hold of Alucard, fling him into buildings, and hold him in place, but at the same time, other wires were cutting him.
* In ''Manga/HunterXHunter'', Machi a member of the Phantom Troupe, is this. She spins her aura into threads in which she uses in a variety of ways, including seaming together dislodged limbs, attaching strands to people in order to track their movement, and as a weapon.
* Yura of the Hair from ''Manga/{{Inuyasha}}''. She use her hair in this mode.
* Belphegor of ''Manga/KatekyoHitmanReborn'' combines this with KnifeNut by attaching wires to each of his thrown knives.
* Chiaki from ''Manga/KamikazeKaitouJeanne'' uses this near the end.
* Before he became a ninja, Dororo of ''Manga/SgtFrog'' was a deadly assassin and this was his trademark weapon.
* Yuuno from ''Franchise/LyricalNanoha'' can use his [[LethalHarmlessPowers Chain Bind]] spell in this manner to slice up anything he chooses. Given the fact that characters in the series tend to shy away from maiming or killing their opponents, he only uses it against [[EldritchAbomination Nachtwal]] during the final battle of ''[[Anime/MagicalGirlLyricalNanohaAs A's]]''.
* Evangeline of ''Manga/MahouSenseiNegima'' likes to use this like PeoplePuppets. She says she can control a total of three hundred people simultaneously within a three kilometer radius (long wires!). She of course uses HermeticMagic to help.
* Nao in ''Anime/MaiHime'' and ''Anime/MaiOtome''.
* One early case in ''Manga/MajinTanteiNougamiNeuro'' involves a decapitation via wire attached to rubber, making a "guillotine slingshot", as Neuro puts it.
* The three Gamia sisters of ''Anime/MazingerZ''. They are three identical, [[GirlishPigtails long-haired]], [[RidiculouslyHumanRobot human-looking]] [[RobotGirl robots]]. Each hair strand of theirs is sharp and can cut through blocks of stone. They showed up again in ''Anime/{{Mazinkaiser}}'' and ''Anime/ShinMazinger''.
* In the Creator/RumikoTakahashi story ''[[Manga/MermaidSaga Mermaid's Scar]]'', CreepyChild Masato strings up piano wire at knee-height to trip the immortal Youta, and, hopefully, [[OffWithHisHead slice his head off]]. Youta receives cuts on his shins and a particularly deep gash on his neck, but is otherwise okay.
* ''Manga/{{Mouse}}'''s arch-enemy One uses lots and lots of this as his weapon of choice.
* This is a [[ImprobableWeaponUser standard weapon]] of some ninja in ''Manga/{{Naruto}}'', though it's rarely used to cut anything, just to restrain opponents and direct/redirect projectiles; [[{{Deuteragonist}} Sasuke]] gets some good use out of them in the earlier parts of the series.
** Chiyo's puppets of Sasori's parents (originally built by Sasori himself) play this straight, as their hands can be attached to each other by wires that can easily cut through enemies by wrapping around them.
* Jubei of ''Anime/NinjaScroll'' keeps his sword wired, so that he can retrieve it quickly. One of the villains also uses wire, mainly as a communication device (similar to a cup-and-string getup), as well as a means to electrocute people.
* Kubinashi from ''Manga/NurarihyonNoMago'' uses razor floss as his weapon of choice.
* The Ordeal of Strings during the Skypeia arc of ''Manga/OnePiece''.
** Donquixote Doflamingo ate the Ito Ito fruit, which allows him to generate razor floss for various purposes. He can cleanly slice through the leg of [[OurGiantsAreBigger Oars Jr.]], attach the wire to his victim's limbs and do PeoplePuppets, and attach it to clouds to swing around like Spider-Man. Considering his vast empire, which spans both halves of the Grand Line and includes [[spoiler:many top-ranking Marines, a lot of World Government officials, a fellow Warlord of the Sea, and even an Emperor]], he is a VisualPun--the man pulling the strings on both the figurative and literal level.
* In ''Manga/RanmaOneHalf'', one of Ranma's enemies, Mon Lon of the Shichifukudojin (or, in dubbed English: Seven Lucky Gods Martial Artists) uses this in the movie ''Big Trouble in Nekonron, China''. And the whole scene was a parody of the fight with God Warrior Mime in the Asgardian arc of ''Manga/SaintSeiya''. It's amazing how much of his [[ClothingDamage clothes get cut]] by the closing loops, but how little of his skin actually breaks, probably because Mon Lon was toying with Ranma at the time. He was actually about to go for the kill when Shampoo intervened.
* Gein from the ''Manga/RurouniKenshin'' manga.
** (Filler) A team of two villainous brothers in ''Manga/RurouniKenshin'' did this so well that the local townspeople thought they were using magic. Kenshin defeated them easily once he recovered his sword- he just cut the strings off.
* ''Manga/SaintSeiya''
** The Asgardian God Warrior Benetnasch Eta Mime, wears a Cloth reminiscent of [[MusicalAssassin a harp]]. As such, he is prone to laying down Razor Floss around the environment as traps, as well as send them flying towards his opponents to entangle them. Note that his harp's strings are strong, and sharp enough, to crack and cut through solid rock, as well as Bronze Cloths and the very human skin of the Saints wearing them.
** In the Hades Saga, the Silver Saint Lyra Orphee has a similar weapon (justified; the character is indeed based on Orpheus from the Greek mythology). He battle another MusicalAssassin, the spectre Sphinx Pharaoh.
** Two minor movie villain: Lyra Orpheus, the Ghost Saint appearing in the first Saint Seiya movie (Lyra Orphee has inspired by him) and one of Abel Saints, Berenice, from thid movie, that has the ability to launch several strands of hair. These hairs Berenices throws are able to trap and disrupt the enemy.
* In ''Manga/ShamanKing'', Lyserg's [[ImprobableWeaponUser dowsing pendulum]] functions as this, when the crystal at the tip isn't being used as a homing dagger.
* Rika from ''Manga/CorpsePrincess'' has a clawed glove that also has razor floss.
* In ''Manga/SilentMobius'', the serial killer Wired used razor floss to chop cops to bits in his rampage.
* WordofGod for ''LightNovel/{{Slayers}}'' is that the Crown Princess of Seillune, Amelia and Naga's mother, created a spell called "Chaos String" that allows the caster to manipulate threads. WordofGod also states that Naga used this spell to kill an assassin that murdered her mother, and that Naga has been terrified of blood ever since.
* Chocolate from ''Manga/SorcererHunters'' is yet another user.
** In the anime, Chocolate's weapon is less the wire and more the long, thin needle attached to it; in the manga, it's straight Razor Floss, with some attention paid to its physics in a few chapters-- it can stretch to incredible lengths and is highly conductive to electricity. Tira has a ''spool'' of it, and at one point uses it to marionette an entire ''casino hall'', resulting in Tira winning a fortune in cheated winnings and the pit boss ending up as party cubes.
* Little Boy in the ''Manga/{{Spriggan}}'' manga uses this briefly to render mook guards into chunks.
* In ''Manga/TekkenChinmi'', Ironfist Chinmi, one of the many evil Kung Fu masters that the titualar character fights uses this weapon as part of his style. Using a single strand of razor floss, he whips it at a target so that it coils around the target's limb, then pulls on it so that it unravels with such speed it cuts flesh. A fairly realistic portrayal in that it only works if he can strike a foe from the side with it- though he is skilled enough with it that, straight on, he can still inflict minor gashes or use it to pierce like a needle.
* Sunny from ''Manga/{{Toriko}}'' can do this with his [[PrehensileHair hairs]].
* In the VideoGame/{{Touhou}} [[{{Hentai}} H]]-[[{{Doujinshi}} doujin]] ''Ningyou Kakumei'', [[{{Yandere}} Alice]] manages to trick the naive [[LivingToys doll Medicine]] into consenting to helping her in her ''[[UnusualEuphemism research]]'' to make a self-capable Doll. As soon as Medicine said that she'd help, Alice traps her with puppeteer's threads:
-->'''Alice:''' It's puppeteer's thread... you'll only cut yourself if you try to struggle... so please be a good doll and stay still...
* In ''Manga/{{Trigun}}'', Vash the Stampede occasionally ties a string to his gun in the anime format, allowing him to retrieve it quickly if disarmed and also, with some simple pulley mechanics, to fire on an enemy from a different angle than the foe expects. In the manga format, Leonof the Puppet Master also uses invisibly thin strings to control his hordes of killer marionettes (in the anime, he apparently just uses remote control). Finally, [[TheDragon Legato's]] ability to control the bodies of his enemies is revealed to work by means of microscopic threads which infiltrate the nervous system and manipulate it by means of electrical pulses.
** Leonof did use wires in the anime; that was where Vash got the idea for the wire-trigger trick.
* The garrotte wire used by Yoji in ''Anime/WeissKreuz'' occasionally functions as Razor Floss, although much more often he simply strangles or restrains people with it.
* In ''Manga/{{X1999}}'', [[spoiler:after Kotori dies by being stabbed in the chest, her body is gruesomely dismembered with this]]. Particularly egregious since it's done with electriclal wires taken from a street post, which are considerably thick... but since the killer was [[spoiler:Fuuma the DarkMessiah]], [[spoiler:he]] probably imbued said wires with [[spoiler:his]] own power.
* In the anime ''Manga/SpaceAdventureCobra'', the Guild pirate Sandra sets a trap inside of a maze for Cobra. The trap was a web of piano wire sharp enough to cut Cobra to limit his movement, while she took pot-shots at him with a lightning gun.
* ''Manga/JoJosBizarreAdventure'':
** During ''[[Manga/JoJosBizarreAdventureBattleTendency Battle Tendency]]'', Joseph Joestar uses ropes doused in oil to trap his vampire enemies and burn them using Hamon. This is foreseen by Esidisi (who also uses this trope via [[BodyHorror 1000 degree blood vessels]]), who cuts the ropes during their battle. Unfortunately for him, Joseph had employed the ''[[https://en.wikipedia.org/wiki/Cut_and_restore_rope_trick cut and restore rope trick]]'' to catch him off guard.
** In ''[[Manga/JoJosBizarreAdventureStardustCrusaders Stardust Crusaders]]'', Joseph gains the Hermit Purple Stand that allows him to create vines out of his hand. However, in this arc it is Kakyoin who best uses the trope with his Hierophant Green Stand, setting countless wires around DIO during their final showdown.
** In ''[[Manga/JoJosBizarreAdventureStoneOcean Stone Ocean]]'', Jolyne ''becomes'' this with her Stand, Stone Free. It unravels parts of her own body into durable strings, which are used in increasingly clever strategies. It further helps that the Stand itself is free to fight off enemies at close range with brute force while Jolyne handles the TrapMaster work.
* The twins Raiga and Fuga from ''Manga/FistOfTheNorthStar'' have this as the basis of their fighting style ''Nishin Furai Ken'' (Dual Gods Wind and Thunder Fist). [[WonderTwinPowers It can only be learned by identical twins]].
** In the anime, their master Sojin uses a style very similar called ''Furai Jukkyoku Ken'' (Wind and Thunder Ten Extremities Fist).

[[folder:Comic Books]]
* Diamond Lil, from ''ComicBook/AlphaFlight'', sometimes plucked a hair from her head and used it as a slicing garrotte. Justified by her being NighInvulnerable, over six feet tall, and very, very strong (thought not superhumanly so). Since it can't be cut, her hair is also very long.
** John Byrne loves this idea, he did the exact same thing with the invulnerable Hardbody from ''ComicBook/NextMen''.
*** And if memory serves he did an issue of ComicBook/FantasticFour where Doctor Doom trapped ComicBook/SheHulk in a cage, the "bars" of which were so thin they sliced into her arm when she tried to push against them.
* In ''ComicBook/TopTen'', the Libra Killer has hundreds of monofilament tentacles, which were even capable of cutting through a phased Jack Phantom.
* [[ComicBook/FantasticFour Super-Skrull]] pulled this off in the [[CrisisCrossover Annihilation Mini]] he received, stretching his body like Reed Richards, but keeping it Thing durability. Razor wire.
* The Franchise/{{Batman}} villain [=KGBeast=] kills a key member of the "Star Wars" missile program this way, hanging wire across the street down which the victim motorcycles. The victim's head is sliced clean off.
* In the Creator/AndrewVachss series ''Cross'', Cross and his crew escape from a juvenile detention center using dental floss to cut the bars on one window. They also dipped to floss in comet cleanser to provide an abrasive. This took some time, with strong guy Rhino chugging away at the floss and Cross reading him poetry to keep him motivated.
** This is actually possible. There are a couple of real life examples of breakouts where prisoners cut through bars with dental floss.
* The [[ComicBook/TwoThousandAD Indigo Prime]] story ''Killing Time'' featured one of the protagonists [[spoiler:executing UsefulNotes/JackTheRipper]] using a harp - however, the strings weren't sharp enough to slice effortlessly through the flesh and needed him to be forced through face first. The fact that harp strings could be strong enough to not only resist breaking but also slowly carve through flesh and bone can be handwaved by the fact that [[spoiler:the harp was from a reality created by an insane omnicidal extra-dimensional monster]].
* Subverted in ''ComicBook/BuckGodotZapGunForHire'', an alien ninja threatens the chief of security with what he assumes is a mono-molecular garrote, but is really just floss.
--> ''[[http://www.airshipentertainment.com/buckcomic.php?date=20080717 Um, that really big threat where I come from.]]''
* In one issue of ''ComicBook/TheFlash'', Doctor Alchemy strung fine wires of pure molybdenum across the shortest path to reach him. Flash realized what was going on and veered off in time, but if he hadn't, he likely would have sliced himself to pieces at the speed he was running at.
* During the ''ComicBook/RogueTrooper'' flashback story, "Cinnabar", Rogue uses a mono-filament wire to cut through parts of Charybdis after his using his rifle only results in the creature's internal defences to [[BlownAcrossTheRoom react violently to gunfire]]. This is ''inside'' the creature. It's noted that a laser would have been more effective, but Rogue's has been confiscated and he was thrown in as part of a BloodSport with minimal equipment.

[[folder:Fan Works]]
* In ''[[Fanfic/GameTheoryFanFic Power Games]]'', Shamal uses her Device's threads to decapitate [[spoiler:a Mariage]].
* ''Fanfic/HarryPotterAndTheMethodsOfRationality'': [[spoiler:Harry]] uses it to finish off several enemies.
* In ''[[https://www.fanfiction.net/s/10917821/1/The-questionable-burdens-of-leadership-of-a-troll-Emperor The (Questionable) Burdens of Leadership of a Troll Emperor]]'', [[OriginalCharacter Setsuna]] kills a [[Franchise/StargateVerse Wraith]] patrol by setting up a monomolecular wire at waist height in one of the hallways. According to her, they likely didn't even feel it until their torsos hit the ground.

* Grids of such wire are used in the ''Film/{{Cube}}'' series to kill off the first character we see in ''Cube''. Many traps in the movie are like this.
* In the film version of ''Film/ForceTenFromNavarone'', Force 10 used the old "wire strung across a road" trick to decapitate a Nazi officer.
* The ''Franchise/{{Predator}}'' employs this on one of the Predator weapons.
** This first appeared in ''Film/{{Predator 2}}''. Basically, the net is made of thin wire and it tightens, cubing the person it captures.
** One of the Predators from ''Film/AVPAlienVsPredator'' used a weapon that fires a net which cuts into a xenomorph's head before being dissolved by the [[AlienBlood acidic blood]], leaving a net patterned scar through the rest of the movie.
* In the opening scene of the horror movie ''Film/GhostShip'', a support wire is used for just the first part of the mass murder.
* In the first ''Film/TheSantaClause'', the magic tinsel employed by the elves to break Tim Allen out of jail.
--> '''E.L.F.S. Leader''': ''Tinsel. Not just for decoration.''
* In the film adaptation of ''Film/JohnnyMnemonic'', the yakuza assassin's monomolecular whip is attached to a giant gold thumbnail rather than the whole digit. It also glows like some sort of laser-whip.
** It was actually a prosthetic thumb, not just a nail. [[{{Yubitsume}} (He'd suffered the loss of his thumb as a result of a previous failure that wasn't serious enough to require his life.)]] It may have glowed to ensure he could see it (or so the audience could see it, or just for RuleOfCool). Another character refers to him having turned a disadvantage (not having the thumb) into an advantage (having a very deadly and hard to remove weapon).
* Mentioned and seen in ''Film/DieHardWithAVengeance''. As the two heroes are attempting to get from a bridge to a ship passing under it, Zeus says they should jump to the attached crane. John [=McClane=] says the cables would cut them in half. Then when they use the winch on an SUV to climb down, the ship pulls the car off the bridge, leaving the hook and cable attached to the crane. As it swings, it hits a henchman. Zeus and John are then seen dragging him by his arms and legs. About eight feet apart...
* A famous scene in the Australian cult classic ''Stone'' involves the murder of a biker by a high-tension wire, followed by his head rolling along the road.
* ''Film/{{Audition}}''. [[{{Yandere}} Asami Yamazaki]] uses piano wire to horrific effect during [[spoiler:the twenty-minute torture sequence that ends the movie]].
* In ''Film/FinalDestination2'' a character is trisected horizontally by a flying wire fence.
* ''Film/MenOfHonor'': In the same vein as many of the listed RealLife examples, Cuba Gooding Jr's character suffered an accident where a large cable snapped, whipping around and injuring his lower leg.
* ''Film/TheThreeMusketeers2011'' had a trap made out of Razor Floss that effortlessly sliced a dropped ribbon into several pieces, filling the dramatic purpose of a LaserHallway.
* In ''[[Film/Piranha3D Piranha 3DD]]'' a character is decapitated by perfectly normal ''bunting'' at neck height when he drives a jeep not particularly fast into it - though given [[BloodyHilarious the nature of the film]] the absurdity is certainly intentional.
** The previous Piranha film features a woman on the receiving end of a DiagonalCut from a high-tension wire.
* Poor [[spoiler:Aimee]] in ''Film/YoureNext'' falls prey to the clothesline version. No decapitation, but the wire cuts deep enough to bleed [[spoiler:her]] to death.
* ''Film/{{Blade}}'' uses this to finally kill TheDragon by decapitation. Of course, the wire in question is silver-lined, as a regular wire would probably not be enough to decapitate a vampire.
* In ''Film/XChange'', Stuart is given a security package at a store that caters to executives and other "corpies". One of the items he isn't yet familiar with is a roll of monomolecular wire held together by a magnetic field. It becomes useful later when he's tied up with his LoveInterest. He has her pull out the roll and use it to cut his bonds. She accidentally slices off a few of his fingers, but it's ok since he's [[BodySurf in the body]] of a clone about to die.
* One of the tasks in ''Film/ThirteenSins'' seems to involve the innocuous task of hanging a metal laundry line. Then, the protagonist realizes that the other end is across the road and some motorcyclists are headed down...
* ''Film/AWalkAmongTheTombstones''. The killers cut off their victim's breasts with a loop of razor wire. During the final confrontation, one of them uses this to garotte two people and nearly makes the protagonist his third, except the muzzle of his pistol gets caught in the loop, preventing the wire from cutting through his throat.
* In ''Film/WrongTurn4BloodyBeginnings'', one victim is drawn and quartered with razor wire, another is hanged and garroted with it, and the {{Final Girl}}s are clotheslined while attempting to escape by snowmobile.
* Henchman Patty O'Brien from the first ''Film/AustinPowers'' film attempts to use this on Austin during an ambush in a casino bathroom. [[{{Swirlie}} Patty fails.]]
** Lampooned in the same film, in which Austin is issued a oral hygiene products. When Austin sees dental floss, he immediately believes it's a disguised garrote wire, but it really wasn't [[ExactlyWhatItSaysOnTheTin anything more than regular dental floss]].

* Creator/PoulAnderson's story "Thin Edge" (written under the pseudonym "Winston P. Sanders") appeared in ''Analog Science Fiction Magazine'' in 1963, possibly making it the UrExample.
* In ''Literature/ABrothersPrice'', when the Whistler family turn in their weapons, a garrotte is among the hidden weapons. As their ancestors were criminals who then got employment as spies, they know how to use all sorts of weapons.
* In ''LightNovel/ALullabySinister'', the Occult Club encounters deadly strands of black hair trying to enter the Surrogate School. Simply touching a strand causes deep lacerations.
* Monomolecular trip wires appeared in Creator/WilliamGibson's ''Literature/CountZero''. In the short story "Johnny Mnemonic," a yakuza assassin has a monomolecular whip attached to the first digit of his thumb. When he pulls on his thumb, the filament extends and the joint becomes the weight for a whip that can [[OffWithHisHead decapitate]] his enemies with one swing.
* The ''Franchise/{{Dune}}'' series included monofilament "Shigawire"; mainly used in recording devices, it also served as a very effective garotte.
* It's used instead of barbed wire around the robotic nursery in the novel version of ''Literature/LogansRun''.
* It was used as a spaceship weapon in the ''[[Series/StarTrekDeepSpaceNine Deep Space Nine]]'' novel ''Objective: Bajor'', where the enemy ships flew out in pairs with a monofilament net between them. The net was so fine it couldn't be seen or blocked by shields, but any ship that was netted simply crumpled to atoms, occupants and all. They also had a net pulled by torpedo, for when the paired ships were split up.
* There's also a scene in ''[[Literature/AlexRider Stormbreaker]]'' where a pair of ATV's try to slice apart our hero with cheese wire in between the two vehicles.
* There's a [[ChekhovsGun Chekhov's]] Razor Floss in Creator/ArthurCClarke's "The Fountains Of Paradise", made of the carbon filament formulated for the space elevator.
* Creator/LarryNiven gives us a couple of examples:
** ''Literature/{{Ringworld}}'': [[http://www.technovelgy.com/ct/content.asp?Bnum=930 shadow square wire]] is a very fine, ''very'' strong wire used to hold the shadow squares that [[AlienSky simulate night on the titular artifact.]] In the first novel the protagonists accidentally collide with a panel before crash-landing on the ring, bringing a mess of it down to the surface. It's practically invisible, and dismembers a lot of people.
** Also from Ringworld: a variable sword is monomolecular wire in a Slaver stasis field (making it rigid and essentially indestructible). Goes through metal like butter.
** Sinclair Molecule Chain in ''Literature/AGiftFromEarth''.
** The whole plot of ''The Descent of Anansi'' revolves around this.
* Featured in the Literature/TomSwift ''IV'' novel ''The Microbots''; Tom wore diamond-coated gloves to handle it. In the novel the characters are miniaturised, at which point the monofilament is thick enough to be safely used as a rope.
* Creator/CarlHiaasen's ''Skin Tight'' features another low-tech implementation of this method, in this case using two trees and some fishing wire.
* The early Creator/OrsonScottCard novel ''Wyrms'' has the heroine keeping a strand of this in her hair for use as a weapon in case of an assassination attempt.
* In Creator/DavidDrake's ''Literature/{{RCN}}'' series, Daniel Leary's retainer, Hogg, experienced poacher, uses lead weights on the end of monofilament fishing line for striking, restraints, and once severed a hand from a wrist.
* In one of L.E. Modesitt's Literature/SagaOfRecluce novels, the heroes set up defenses involving razor floss strung along paths down which the enemy cavalry would charge.
* In Creator/AlastairReynolds' ''[[Literature/RevelationSpaceSeries Absolution Gap]]'', one of the bad guys has an artificial hand with razor floss built into it.
* In ''Literature/TheCityWhoFought'' by Creator/AnneMcCaffrey and Creator/SMStirling, Joat, a young girl, sets up several strands of monofilament wire across a corridor than baits a Kolnari patrol to chase her, running into the trap. The Kolnari are literally sliced to pieces by the molecule-thick wire, making for a gruesome, bloody scene. As Joat says, it "...gives a new meaning to 'cut off at the knees!'"
* The third episode of Dan Simmons' ''Literature/HyperionCantos'', ''Endymion'', features monofilament wire used as a tripwire in an ambush. It was also conveniently hidden in a spool of sewing thread.
* The short story "[[Literature/OutboundFlight Mist Encounter]]" has Thrawn running rings around the Imperials sent to investigate his place of exile, then calmly explaining exactly how and what he did to the captain. One of the many things he did was cause a TIE fighter to crash.
-->'''Mitth'raw'nuruodo''': I knew the spacecraft would come to search. In preparation, I had strung some of my monofilament line between two of the taller treetops. One of the spacecraft hit it.
* Literature/TheStainlessSteelRat encounters an assassin using monofilament wire, but only to lower himself to a balcony where his target is. Jim [=DiGriz=], who's working as a bodyguard of the target, has to drop several stories onto the balcony to stop him, as an attempt to climb down the wire would slice his hands open.
** From ''West of Eden'' and its sequels by the same author, monofilament knives are the standard cutting tools for Yilane (basically intelligent tool-using dinosaurs).
* ''Brotherhood of the Rose'' by David Morrel. One of the protagonists is being garroted by a fellow assassin; it's mentioned that such wires are embedded with diamond so it can saw through fingers if the mark is able to get them in the way in time. This is what begins to happen, but fortunately he's able to break free before then.
* Combat Drones deployed by Literature/TheCulture occasionally use ''monofilament warps'' stretched between two remote controlled projectiles. The filaments seem capable of cutting through most conventional materials with no effort.
* References abound in the [[Literature/TheExecutioner Executioner]] series to guards having their throats cut open with piano wire garrotes, while monofilament trip wires were often mentioned in the ''Literature/AbleTeam'' series.
* In Creator/DanAbnett's Literature/GauntsGhosts novel ''Salvation's Reach'', the assassin used wire as a garotte.
* In Creator/DianeDuane's ''Literature/TheRomulanWay'', [=McCoy=]'s Romulan captors bind his hands with a ribbon with a monofilament at the center. It's perfectly safe if he doesn't fight it...and if he does, his hands fall off.
* In Eric Nylund's ''Mortal Coils'', Fiona Post's special ability is the power to cut through anything with she is holding at the time provided it's thin enough. She uses a rubber band, yo-yo string and her own hair throughout the novel to do this. Supposedly her mother was possessed of the same ability.
* Isabelle Lightwood from ''Literature/TheMortalInstruments'', edges her whip. [[spoiler:She uses it to take off Sebastian's hand in ''City of Glass'']].
* Jessamine Lovelace from ''Literature/TheInfernalDevices'', edges her parasol, turning it into an effective weapon.
* Alex Fierro's signature weapon in ''Literature/MagnusChaseAndTheGodsOfAsgard'' is an enchanted pottery wire. It's magically extendable and can cut through boulders, but not always magical beings. [[CombatPragmatist Still makes an excellent garrotte in those cases]].
* Trent the Uncatchable uses "fine-line" multiple times in ''Creator/DanielKeysMoran'' "Tales of the Continuing Time". One of his more creative uses was to string it across the hatches of missile bays in a space station that he was about to escape from. When the space station fired the missiles at his ship, they were to be cut in half by the fine-line before it melted due to the rocket exhaust, causing the missiles to explode and destroying that wing of the space station, in an attempt to prevent future launches against him. In order to prevent any deaths (even of his enemies, since Trent is a pacifist), he told the commander of the space station what he had done prior to launch. Unfortunately, the bad guy is extremely smart, and ripple-fired all of the missiles at once. Most were destroyed, but enough got through to damage Trent's ship.

[[folder:Live-Action TV]]
* In one episode of ''Series/DadsArmy'' Captain Mainwaring describes the use of cheese cutters as a garrotte, causing Private Pike to become ill. Sgt. Wilson suggests it's because Pike hates cheese, rather than Mainwaring's mention of decapitation.
** Also notable as a subversion -- when Mainwaring actually tries to demonstrate the technique in mid-air and ends up pulling too hard, the wire snaps and breaks out of the handle.
--->'''Mainwaring:''' Instant decap- * wire snaps* oh.
* The CIA in ''Series/DeadliestWarrior'' use a garrote made from piano wire as their close-range weapon against the shoe knives used by the KGB. In the test, the wire showed itself capable of beheading a ballistic gel dummy. The battle simulation between the two groups ends with [[spoiler:the last CIA agent waiting in the last KGB agent's car until he gets a chance to slice his throat with the wire.]]
* In one ''Series/{{Bones}}'' episode, the murderer was a sculptor who, driven to rage by his neighbour's singing, garotted him with a sharp wire he used to cut clay.
* The "wire strung across the road" trick was used in a ''Series/MidsomerMurders'' episode to decapitate a motorcycle rider.
** And in a ''Series/OneThousandWaysToDie'' episode, "Golden Die-Angle", a drug enforcer is decapitated in the same way while riding an ATV.
* An episode of ''Series/DarkAngel'' had a police officer recount how some firemen got their throats slit by piano wire strung across doorways.
* An episode of ''Series/{{Angel}}'' had Angel and Spike pull this trick on a supposedly-unbeatable guardian.
* Jerri relates a story on an episode of ''Series/StrangersWithCandy'', in which a guy-wire slices Bongles the clown in two at the circus; leaving "two, small, dead clowns."
* ''Series/{{Andromeda}}'' had the M-lash, a molecule thin whip that was so sharp if you tried to set it down with out turning it off first it would cut through the table, then the floor, etc.
** Dylan even comments on this questioning the intelligence of an opponent who would use such a weapon onboard a spaceship
* The first episode of ''Series/FoylesWar'', "The German Woman", involves a particularly cruel case of this. While out riding her horse, the titular German woman hits a length of wire strung between two trees at neck height. Foyle kindly explains to us later that - unfortunately for her - it doesn't result in complete decapitation, and she is simply left to bleed to death on the ground.
* In ''Series/AgentsOfSHIELD'' [[spoiler:Ward uses this to kill Eric Koenig. While not actually seen, when Simmons does the autopsy she notes that it was a struggle and the killer must have been both physically strong and significantly taller than the victim, so this is a fairly realistic portrayal.]]
* Renge in Series/KamenRiderKabuto uses this as her signature weapon.
* In ''Series/BoardwalkEmpire'', a gang enforcer garrottes another man with a wire cutter. While he has to use much more force than usual for this trope, he ''does'' manage to garrotte the man through his fingers, leaving them severed on the floor.
* An episode of ''Series/{{NCIS}}'' had a killer who used a [[ImprobableWeaponUser motorized garrote]]; just start the motor and the wire would tighten over whatever it was placed on. Yes, ''what''ever--at one point she set the device [[MundaneUtility on the handles of a pair of double doors]] in order to keep Gibbs in a room long enough to make her escape.
* The ''Series/CSIMiami'' episode "High Octane" begins with young adults performing automobile stunts in a beach parking lot. One driver, who's sitting on the roof of his car as he uses his feet on the steering wheel, [[OffWithHisHead gets decapitated]] when[[spoiler:, after a saboteur remotely elevates his car high enough,]] an electrical wire (connected to a string of lights) cuts clean through his neck at 40 miles per hour.

[[folder:Tabletop Games]]
* ''TabletopGame/EclipsePhase'' makes use of monofilament garrotes as a very effective hand to hand weapon, but they break after one use. In the opening fiction, one of the Firewall Sentinels unknowingly puts her hand right through a web of monomolecular wire strung across a hallway by TITAN self-replicating nanoswarms; she doesn't even notice it has happened until her hand falls apart in front of her eyes.
** The game also has more durable monofilament swords, competing with diamond-edged axes (which do more damage but have lower AP) for best bladed weapon, up until ''Firewall'' introduced [[LaserBlade plasma swords]].
* ''TabletopGame/{{Shadowrun}}'' had monofilament swords and whips and used monofilament in traps. Judging from the hacker chatter in some of the {{Sourcebook}}, though, the monofilament whip is looked at as something of a fool's weapon, since an untrained user is as likely to decapitate himself as his enemy. This never gets reflected in game rules, of course, although it does suggest a truly evil result when the "[[CriticalFailure Rule of Ones]]" comes into play.
** The 4th edition of ''Shadowrun'' does give explicit rules for what happens when someone botches a monowhip attack. It's pretty nasty.
*** This is, however, made up for by the fact that the Monofilament Whip is arguably the single best melee weapon to use against an armored opponent due to it having excellent damage, long reach, and very good armor penetration.
** One of the sourcebooks also made fun of the use of the term "monofilament" with the chatter at the bottom of the monofilament sword entry commenting that his shoelace is monofilament (one piece) too, but it doesn't cut through anything.
*** Specifically, it pointed out the difference between any old monofilament, and a monomolecular monofilament. Much of the gear in that particular sourcebook fell into either the AwesomeButImpractical or completely foolish categories.
** In 3rd Edition, whips (including the monofilament variety) had a chance to strike the wielder if the target dodged (rather than the wielder just missing).
** ''Videogmae/ShadowrunReturns: Hong Kong'' adds the whip as a optional cyberware weapon implant. It can penetrate and degrade armor, has decent reach (it's treated as a short-range gun by the game mechanics, though it has a hard limit on attack distance), and can cause bleeding. It cannot, however, hurt you if you miss.
* ''TabletopGame/AnimaBeyondFantasy'' sourcebook ''Dominus Exxet'' features legendary weapons corresponding to the zodiac. Cancer's weaopn is a large array of razor floss.
* The Eldar of ''TabletopGame/Warhammer40000'' are fond of monofilament wire. Their jump troops, the Warp Spiders, are armed with a gun that fires it, and their artillery is armed a much larger version of this gun that fires a cloud of the stuff, which then drops down on enemy troops and shreds them. Most notably are the Harlequins, who use a weapon called the "Harlequin's Kiss", a device that inserts a single monofilament wire down your throat and whips around at incredible velocity, which is effective, needless to say. The Eldar are [[BlackAndGrayMorality still considered one of the more noble races in the setting]], [[CrapsackWorld which says a lot about what kind of universe this is]].
* List of ''Blog/ThingsMrWelchIsNoLongerAllowedToDoInAnRPG [[http://theglen.livejournal.com/131998.html (1001-1250)]]'' reminds us for a reason that
--> 1032. Monofilament does not automatically make the world a better place.
* In Creator/{{TSR}}'s short lived RPG ''TabletopGame/{{Alternity}}'', there was a particular type of villain named the "kroath" who made use of monofilament wire to set up traps. On a good roll, the material was capable of killing [=PCs=] in one attack.
* ''TabletopGame/{{GURPS}}'' finds a bunch of clever uses for monowire from whips to swords to fences to bullets. There's also a superior version called nanothorn which is like monowire but doesn't cut things so much as it ''dissolves'' them by slicing their molecular bonds.
* ''TabletopGame/DungeonsAndDragons''
** [[SiliconBasedLife Crystal spiders]] from TabletopGame/DarkSun make glass webs that are razor sharp, near-invisible, very strong ''and'' entangling (though not sticky as such) at once.
** The spider-like Head Hunter in TabletopGame/{{Ravenloft}} spins webs of this stuff--usually right at neck level. Being so thin, they're near-invisible...
* R. Talsorian Games' ''TabletopGame/{{Cyberpunk}}'', supplement ''Chromebook 2''.
** The Kendachi Monowhip is extended from a handle, with a weight at one end for so it can be swung. It can be extended up to 4 meters and reeled back in by pushing a button. It cuts through all organic materials and most plastics, and reduces armor to 1/3 its normal value.
** The Kendachi Monowire is similar, but has a weight at each end. It can be used for setting up traps and as a garrote.
* ''TabletopGame/{{Traveller}}'', ''Megatraveller Journal'' #3 adventure "Rapid Repo". The {{PC}} team can requisition monomolecular garottes which are really good at slicing through victims (and their armor).
* Blade (Flying Buffalo)'s original ''TabletopGame/GrimtoothsTraps'' (1981). The Delvermatic Dicer trap pushed a door-opening {{PC}} through a fine monofilament mesh, which was described as having a "cheese grater" effect on the {{PC}}'s body (i.e. it left them lying on the ground in chunks).
* ''TabletopGame/{{Dragonstar}}'' has monofilament axes (and dwarven urgroshes).
* Judges Guild magazine ''The Dungeoneer Journal'' #23, article "Magic Item Generator". One of the possible magic items is a Monomolecular Wire that's a [[SharpenedToASingleAtom single molecule thick]]. It can cut through any substance but must be anchored at each end to be used as a weapon (e.g. as a garotte).

[[folder:Video Games]]
* Marcy from ''VideoGame/ChronoCross'' utilizes string-based attacks as her techs, for cutting, sending energy bursts through them and even shifting earth.
* ''{{VideoGame/Dishonored}}'''s Spring Razors are basically spring-loaded razor wire landmines.
* Sima Yi uses "wired gloves" gauntlets fitted with razor floss as his primary weapon in ''VideoGame/DynastyWarriors 6'', ostensibly to symbolize his PuppetMaster tendencies. He abandons them from the 7th game onwards, but ''8'' passes them on to his wife Zhang Chunhua.
* Agent 47 from the ''VideoGame/{{Hitman}}'' series has a garrotte wire as his second signature weapon. It does not leave blood unlike knives, and is the best weapon to use as a Silent Assassin.
** ''{{Manhunt}}'' also has a barbed wire garrotte.
* Sion's Etherite from ''VideoGame/MeltyBlood'' is not only used as a Razor Floss weapon, but can also be ''inserted into people's nervous systems'' to allow her such abilities as reading their thoughts and [[PeoplePuppets controlling their bodies]].
* [[VideoGame/MegaManStarForce Harp Note]] has this as one of her attacks. After binding you with her guitar strings, she [[MusicalAssassin riffs a few times]]. [[ThePowerOfRock It hurts]].
* Sonya Blade utilizes this as a fatality in ''VideoGame/MortalKombat9''. In ''Videogame/MortalKombatX'' she uses the wire as a grappling tool.
* Kurenai, from ''VideoGame/RedNinjaEndOfHonor'' uses a tetsugen, or an iron wire.
* [[MsFanservice Kasuga]] from ''Videogame/SengokuBasara'' uses these as well as Kunai tied to the end.
* ''VideoGame/{{Syndicate}} Wars''. Being the classic monofilament stuff, Razor Wire is really hard to spot and is laid down as traps in alleys to hamstring unsuspecting runners. Its badder brother Trigger Wire is as difficult to notice and supposedly adds explosions.

* [[Literature/JeevesAndWooster Reginald Jeeves]] (yes, you read that right) in ''Webcomic/AndShineHeavenNow'': in fact, he was the one that taught [[Anime/{{Hellsing}} Walter]] how to use them.
* Butch from ''Webcomic/ChoppingBlock'' [[http://choppingblock.keenspot.com/d/20101222.html has some fun]] with wires on a ski slope.
* Spoofed in [[https://cad-comic.com/comic/the-more-you-know-2/ this strip]] of ''Webcomic/CtrlAltDel'' where the author puts forth his theory of why headshots in ''VideoGame/Fallout3'' tend to decapitate enemies.
* ''Webcomic/NeverMindTheGap'' has ''living'' monomolecular wire. It was introduced cutting off a robot's metallic fingers.
* Captain Tagon from ''Webcomic/SchlockMercenary'' has a "Dorothy System" in his boots. He clicks his heels together, and it strings a mono-wire between them. This makes a dandy surprise weapon. He's used it to disarm Schlock - literally ([[GoodThingYouCanHeal he got better]]). He later uses it to decapitate Elf so that he can put her head into suspended animation and get her safely back to the ship before his last stand in one of the Schlocktoberfests.
** Supposedly it was named for [[Film/TheWizardOfOz Dorothy's]] magic slippers. She would click her heels together and say "there's no place like home." With this weapon you need not say anything, although users do tend to say things like [[BloodyHilarious "eewww"]].

* The ''WebOriginal/OrionsArm'' universe has [[AppliedPhlebotinum magmatter filaments]], useful for making things like Ringworlds due to their vast strength to weight ratio. They're actually thinner than single atoms of normal matter and can trigger subatomic particle decay if they intersect an atomic nucleus. Yep, it can cut ''protons'' into pieces.
* In ''Literature/{{Worm}}'', [[spoiler:Skitter]] uses [[spoiler:Clockblocker]]'s power to make one of these suspended in air for her opponent to crash into.
* Mary in ''Literature/{{Twig}}'' makes heavy use of this, generally wrapping it around the handles of her knives so she doesn't cut herself-which also conveniently allows her to stab people. At one point she stabs an enhanced opponent with several knives and then uses the wire as footholds to climb around, while it cuts into them the more pressure she places on it.

[[folder:Real Life]]
* The low-tech "wire strung across the road" trick was a means of guerrilla warfare in times when most officers and messengers went about at high speeds on horseback. In many versions of the Headless Horseman myth, this is how the Hessian mercenary that became the Horseman originally lost his head. Later it would find use in World War 2 on soldiers of both sides riding either motorcycles or open top vehicles like Jeeps. This trick was also taken up by the IRA during UsefulNotes/TheTroubles.
** If you look in better done movies or old war films, you'll see an A-frame device on the front of jeeps and such. Those were used to cut wires by channelling them up into a cutting notch. There are similar devices on modern helicopters, as well as in wire-on-parachute shells and cables of anti-aircraft balloons.
** Also a danger in the Florida Everglades and other swampy areas in which barbed wire has been strung across an area. Most of the giant fan-driven swamp boats will have a cutter in the front to prevent unanticipated decapitations.
* Razor wire, a more advanced version of barbed wire, is used in trench warfare to stop infantry movement. It is still in use to prevent people from climbing fences, or to prevent cattle from trying to get through a fence.
** Barbed wire or razor wire is nearly harmless when tightened properly into a fence - farm animals will stop against it, but any man with reasonable agility can push the wires aside and sneak through. Wire used in [[UsefulNotes/WorldWarOne trench warfare]] was differently deployed, in large loose coils, like on top of modern prison walls. Most people trying to sneak through would get entwined, their thick uniforms and loose gear being easily caught in the wire, and if razor wire was used, they cut themselves trying to escape.
* Partial TruthInTelevision: British secret agents during WWII were rumored to use so called ''Gigli saw'' -- a thin, flexible wound-wire saw with embedded diamond or corundum dust, widely used in surgery for bone-cutting -- as a shoelaces. Very similar in thickness and construction to a piano string (it could be substituted by the one in a pinch, in a matter of of fact), it could be easily used for garroting (which requires kinking the victim's windpipe), but just pull it by one side and OffWithHisHead
** They're also used to cut pig tusks, but this can lead to potentially lethal results.
* Cheese wire can do a lot more damage to non-cheese materials than you might think.
* Any wire, or even occasionally rope on a ship is a potential case of this. Get your arm tangled in a spool of wire attached to something heavy (say, a sail or fishing net), lose control of it and ''rrrrip''. This can strip flesh from bone - or even in some cases, tear limb from body. Either make sure whatever connects the wire to the heavy thing will snap before you do, or know exactly what you're doing when handling wire.
** Even worse, high tension cables, chains and ropes that snap in industrial accidents. Since they're designed to withstand many thousands of pounds of stress, all that energy goes directly into both halves of the line, which can also weigh hundreds of pounds by themselves, whipping chaotically to strike or slice clean through anything within the arc circumscribed by their unspooled length around their anchoring points.
** Ditto the arresting wires on CATOBAR [[CoolBoat aircraft carriers]]. They are inspected daily. Having one of them snap is a very bad thing. There is footage of such a snap occurring on a flight deck, and a quick-thinking crewman jumps the cable as it passes, avoiding being bowled over by it.
** During the filming of the unfinished ''[[Film/GoneInSixtySeconds1974 Gone in 60 Seconds 2]]'', a cable that was supposed to pull down a water tower snapped and felled a telephone pole, fatally crushing filmmaker H.B. Halicki.
* The Italian mafioso Vincenzo Curcio escaped from prison in Turin by sawing through the bars with dental floss. This was possible because the bars were made of iron low in carbon, which was easy to saw through, and him adding tooth powder (an abrasive that used to be more commonly used for dental cleaning) on the wire, increasing the grinding power.
* The Indian ''[[WhipSword chuttuval]]'' is basically made of flat, sharpened wire.
* You can supposedly spot deep sea fishermen who've carelessly wrapped the line around their hand when reeling in a big fish. They're missing fingers.
** Same goes to lassos carelessly used by cowboys, charros, huasos, etc.
* That's why archers' equipment includes bracers (and protection for fingers, in some styles): no one wants to lose the skin of their arms, palms, fingers or wrists to a misbehaving bow string.
* The infamous kite string known as "hilo curado" ("charged string") in Chile and "cerol" in Brazil, used to have kites fly and cut each other's strings. Basically, it's normal kite thread covered in liquid glue and pulverized glass. It's ''dangerous as hell.'' People die: onlookers, participants, people who are just in the wrong place at the wrong time will get [[OffWithHisHead their throats slit]] by a kite with strings like these passing by. This style of kite combat is actually fairly common all over the world, but especially popular in the two aforementioned countries.
** It was so bad in Brazil a few years ago, that the electricity company had some ads against it because it can cut through power cables and kill the kite flyer [[ElectricTorture by electrocution.]] Same goes to Chile: since kite flying/fighting is very common in September (during the national holidays), ''every'' September new ads against "hilo curado" are released on Chilean TV, and ''many'' kite vendors are detained for making it. It's gotten to the point that getting caught with a roll of this kind of string will net you a bigger fine than getting caught with ''drugs''.
** The novel ''Literature/TheKiteRunner'' focuses upon them a lot in the first (and in the last) chapters.
* This is basically the theory behind the rope saw.
* Simple monofilament fishing line, the stronger types in particular, can certainly be used like this (intentionally or otherwise). In addition to the above examples, it can also be used like a rope/wire saw (and can cut through PVC pipe, in fact). And for those fishermen stranded in the wilderness...strong, nearly-invisible line is perfect for making snares to catch a meal. Just don't [[HilarityEnsues forget where you left the traps]]...
* It's worth mentioning carbon nanotubes. The longest ones are 18cm long right now, but they're getting longer and cheaper all the time. One tube has a width of only a few nanometers, and the bonding used to hold the tube together means that the tubes are harder than diamond and have a higher tensile strength than almost any other material. Also, given its structure, it really is a true monomolecular filament as fiction imagines them; application of proper force would let one slice through just about anything like a hot knife through butter.
* The winch cable they use to launch gliders can be quite dangerous. It's a kilometer long cable moving at high speed, and there are stories of it slicing cows in two when the unlucky beasts wander onto airfields. The cables have a parachute at the end so that they fall gently after being disconnected from the glider after takeoff. If the cable breaks during takeoff, it can snap to the ground with great force, so the winch itself is usually armored or at least has reinforced bars on the windows.
* Executing a person by hanging is actually a tricky procedure. The length of rope selected for the execution must be carefully calibrated to the weight of the condemned so the neck will break upon drop, killing them instantly and cleanly. The most commonly seen mistake in movies is to make the length too short, slowly choking the victim to death. However, a too-long rope can easily turn a clean hanging into a messy decapitation. This infamously happened to the western outlaw Tom Ketchum.
* Similar to the industrial cable example above: nylon mooring lines (the ropes used to tie ships to a pier) are extremely dangerous if pulled too tight. Nylon can stretch quite a bit and if the line snaps it will go whipping across the deck, easily killing or dismembering anyone in its path.
* Not a rope or a cable, but in terms of skinny floppy slicey things [[http://en.wikipedia.org/wiki/Paper_cut it's entirely possible you've witnessed or inflicted a paper cut]]. Though rarely intentional or even close to lethal, they ''are'' painful, since the cuts are shallow and on the fingers or palms (meaning they encounter a lot of nerves). High-quality paper for color laser printers is the worst, as it is both unusually rigid and thinner than photo paper, writing paper or cardboard.
** It is also possible to get such a cut from corrugated cardboard (which has a paper surface on each side). While generally harder to cause, they can be much deeper and more dangerous cuts as the distance the cardboard can slide while cutting has the potential to be a few feet, rather than a few inches.
* Chips in your computers were cut to size using wire. The silicon crystals are cut into wafers (for chip manufacturing) by using a wire saw. It uses metal wire and a suspension of abrasives (diamond powder etc.) in water. It works a bit like an egg slicer, cutting many wafers at once from a single block.
* A cruder version of the trope is chain, bar, or wire shot. Think two balls or half-balls with something strung between them. Fire out of a smoothbore and watch the thing flail. While the ball(s) are deadly, the real business end is the thing between them, carried by the inertia of the ball(s) to provide a surprising amount of cutting power. Chain and bar shot were meant for use against masts and rigging on ships while wire shot is their evolution into a shotgun shell.
