Razor Floss
He is not a seamstress.

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

Razor floss is when any long, thin material — string, thread, fine wire, etc — is used as a weapon with Absurd Cutting Power. Odd as it may sound, strings can become deadly weapons in the right hands. Besides restraining enemies and even 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 monomolecular wire. In series less reliant on the Rule of Cool, the wire usually manifests as garrotes or tripwires, with varyingly messy outcomes.

What the audience sees usually amounts to Sword Lines sans the sword. Can be counted on to inflict an absurdly Clean Cut 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.

Compare Whip Sword and Killer Yoyo. Subtrope of Absurd Cutting Power.

    Anime and Manga 
  • The titular character of the Boogiepop Series wields this quite efficiently and lethally.
  • Walter C. Dornez of Hellsing is a prominent example. With ten monomolecular filament wires, he can obliterate armies of the undead. After his Face-Heel Turn, he can slice buildings to pieces and mesh his wires into barricades. He also takes up puppetry.
    • It's a bit odd. If something even accidentally comes in contact with it, it's cut very cleanly, but when he was 14, he was seen using it to grasp a pack of cigarettes. 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.
  • Yashamaru of Basilisk.
  • Yura of the Hair from Inuyasha.
  • Gein from the Rurouni Kenshin manga.
    • (Filler) A team of two villainous brothers in Rurouni Kenshin 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.
  • One episode of Cardcaptor Sakura 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.
  • In X1999, this is the way Kotori dies Particularly egregious since it's done with electriclal wires taken from a street post, which are considerably thick.
  • 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 Saint Seiya. It's amazing how much of his clothes get cut by the closing loops, but how little of his skin actually breaks.
  • The three Gamia sisters of Mazinger Z. They are three identical, long-haired, human-looking robots. Each hair strand of theirs is sharp and can cut through blocks of stone. They showed up again in Mazinkaiser and Shin Mazinger.
  • Bishōnen Benten from Cyber City Oedo 808 used this as his weapon of choice, slicing through bad guys quite stylishly.
  • Kazuki from Get Backers (pictured), 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 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.
  • Razor Floss is one of Amagumo/Rain Spider's many, many weapons in Desert Punk. He even compares it to a spider's web.
  • Nao in Mai-HiME and Mai-Otome.
  • The garrotte wire used by Yoji in Weiß Kreuz occasionally functions as Razor Floss, although much more often he simply strangles or restrains people with it.
  • L.A. from El Cazador de la Bruja is freakishly efficient with this weapon.
    A random cop: Get forensics down here ASAP. Uh, someone who's good at puzzles...
  • Chocolate from Sorcerer Hunters 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.
  • One early case in Majin Tantei Nougami Neuro involves a decapitation via wire attached to rubber, making a "guillotine slingshot", as Neuro puts it.
  • The main weapon of Elf and Zwolf in Battle Angel Alita: Last Order usually in tandem. They've used it for defensive traps,deadly "cat's cradle" attacks,helping with Sechs' Fastball Special and... knitting a scarf supersonically in the middle of a tournament.
  • This is a standard weapon of some ninja in Naruto, though it's rarely used to cut anything, just to restrain opponents and direct/redirect projectiles; 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.
  • Lyserg's dowsing pendulum functions as this, when the crystal at the tip isn't being used as a homing dagger.
  • Evangeline of Mahou Sensei Negima! likes to use this like People Puppets. She says she can control a total of three hundred people simultaneously within a three kilometer radius (long wires!). She of course uses Hermetic Magic to help.
  • As stated above, Saint Seiya, the Asgardian God Warrior Benetnasch Eta Mime, wears a Cloth reminiscent of 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 Rumiko Takahashi story Mermaid's Scar, Creepy Child Masato strings up piano wire at knee-height to trip the immortal Youta, and, hopefully, slice his head off. Youta receives cuts on his shins and a particularly deep gash on his neck, but is otherwise okay.
  • One character in Bastard!!!! has this as a main weapon.
  • Triela makes use of one of these to strangle a guard in an episode of Gunslinger Girl.
  • Belphegor of Katekyo Hitman Reborn! combines this with Knife Nut by attaching wires to each of his thrown knives.
  • Jenos Hazard from Black Cat 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.
  • Gundam X has a 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 Attack Drone-type weapons.
  • Before he became a ninja, Dororo of Keroro Gunsou was a deadly assassin and this was his trademark weapon.
  • In the Touhou H-doujin Ningyou Kakumei, Alice manages to trick the naive doll Medicine into consenting to helping her in her 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 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, 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.
  • Jubei of Ninja Scroll 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.
  • The Ordeal of Strings during the Skypeia arc of One Piece.
    • 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 Oars Jr., attach the wire to his victim's limbs and do People Puppets, 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 many top-ranking Marines, a lot of World Government officials, a fellow Warlord of the Sea, and even an Emperor, he is a Visual Pun—the man pulling the strings on both the figurative and literal level.
  • A frequent murder weapon in Detective Conan — in fact, the first case solved involved a beheading on a roller coaster using monofilament wire.
  • The first Appleseed movie had a pair of gynoids with cutting whips that did quite a number on Hitomi's car and later on Briareos' Hand Cannon as well.
  • Wordof God for The 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. Wordof God 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.
  • In To Aru Majutsu no Index, Kaori uses this to simulate super fast sword strikes.
  • In 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.
  • Little Boy in the Spriggan manga uses this briefly to render mook guards into chunks.
  • In Hunter × Hunter, 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.
  • Mouse's arch-enemy One uses lots and lots of this as his weapon of choice.
  • In an episode of Yami No Matsuei, Muraki uses this against Hisoka. Not only that, but he ties up Hisoka to a wall with razor so, if he tried to free himself, he'd get cut. YEOWCH.
  • Surprisingly enough, this appears in Haruhi-chan. Yuki uses it to restraint a mutant Santa Claus.
  • Chiaki from Kamikaze Kaitou Jeanne uses this near the end.
  • Rika from Shikabane Hime has a clawed glove that also has razor floss.
  • Kubinashi from Nurarihyon No Mago uses razor floss as his weapon of choice.
  • A brief murder mystery in Gosick involved a motorcyclist who was beheaded by a strand of wire stretched across the road.
  • Showed up once in the manga version of City Hunter, when Ryo had to deal with a killer dosed with Angel Dust: due the drug the killer stood back up after getting shot three times with a Colt Python .357 Magnum, at which point Ryo pulled out a wire and beheaded him.
  • Sunny from Toriko can do this with his hairs.
  • Alice Fuji from Arachnid has a blade attached to thread that when shot bounces off walls and spreads webs for detecting and capturing enemies.
  • In Silent Mobius, the serial killer Wired used razor floss to chop cops to bits in his rampage.

    Comic Books 
  • Diamond Lil, from Alpha Flight, sometimes plucked a hair from her head and used it as a slicing garrotte. Justified by her being Nigh Invulnerable, 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 Next Men.
      • And if memory serves he did an issue of Fantastic Four where Doctor Doom trapped She-Hulk in a cage, the "bars" of which were so thin they sliced into her arm when she tried to push against them.
  • In Top 10, the Libra Killer has hundreds of monofilament tentacles, which were even capable of cutting through a phased Jack Phantom.
  • Super-Skrull pulled this off in the Annihilation Mini he received, stretching his body like Reed Richards, but keeping it Thing durability. Razor wire.
  • The 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 Andrew Vachss 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 Indigo Prime story Killing Time featured one of the protagonists executing Jack the Ripper 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 the harp was from a reality created by an insane omnicidal extra-dimensional monster.

    Fan Works 
  • In Power Games, Shamal uses her Device's threads to decapitate a Mariage.

    Film 
  • Grids of such wire are used in the 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 Force Ten From Navarone, Force 10 used the old "wire strung across a road" trick to decapitate a Nazi officer.
  • The Predator employs this on one of the Predator weapons.
    • This first appeared in Predator 2. Basically, the net is made of thin wire and it tightens, cubing the person it captures.
    • One of the Predators from Alien vs. Predator used a weapon that fires a net which cuts into a xenomorph's head before being dissolved by the acidic blood, leaving a net patterned scar through the rest of the movie.
  • In the opening scene of the horror movie Ghost Ship, a support wire is used for just the first part of the mass murder.
  • In the first The Santa Clause, 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 Johnny Mnemonic, 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.
  • 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.
  • Audition. Asami Yamazaki cuts off body parts by using piano wire.
  • In Final Destination 2 a character is trisected horizontally by a flying wire fence.
  • Men of Honor: In the same vein as many of the listed Real Life examples, Cuba Gooding Jr's character suffered an accident where a large cable snapped, whipping around and injuring his lower leg.
  • The Three Musketeers (2011) had a trap made out of Razor Floss that effortlessly sliced a dropped ribbon into several pieces, filling the dramatic purpose of a Laser Hallway.
  • In 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 the nature of the film the absurdity is certainly intentional.
  • Poor Aimee in You're Next falls prey to the clothesline version. No decapitation, but the wire cuts deep enough to bleed her to death.

    Literature 
  • Poul Anderson's story "Thin Edge" (written under the pseudonym "Winston P. Sanders") appeared in Analog Science Fiction Magazine in 1963, possibly making it the Ur Example.
  • Monomolecular trip wires appeared in William Gibson's Count Zero. 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 decapitate his enemies with one swing.
  • The 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 Logan's Run.
  • It was used as a spaceship weapon in the 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 Stormbreaker where a pair of ATV's try to slice apart our hero with cheese wire in between the two vehicles.
  • There's a Chekhov's Razor Floss in Arthur C. Clarke's "The Fountains Of Paradise", made of the carbon filament formulated for the space elevator.
  • Larry Niven gives us a couple of examples:
    • Ringworld: shadow square wire is a very fine, very strong wire used to hold the shadow squares that 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 A Gift from Earth.
    • The whole plot of The Descent of Anansi revolves around this.
  • Featured in the Tom Swift 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.
  • Carl Hiaasen's ''Skin Tight' features another low-tech implementation of this method, in this case using two trees and some fishing wire.
  • The early Orson Scott Card 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 David Drake's 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 Saga of Recluce novels, the heroes set up defenses involving razor floss strung along paths down which the enemy cavalry would charge.
  • In Alastair Reynolds' Absolution Gap, one of the bad guys has an artificial hand with razor floss built into it.
  • In The City Who Fought by Anne McCaffrey and S.M. Stirling, 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' Hyperion Cantos, 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 "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.
  • The Stainless Steel Rat 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 The Culture 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 Executioner series to guards having their throats cut open with piano wire garrotes, while monofilament trip wires were often mentioned in the Able Team series.
  • In Dan Abnett's Gaunt's Ghosts novel Salvation's Reach, the assassin used wire as a garotte.
  • In Diane Duane's The Romulan Way, 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.
  • The Mortal Instruments: Isabelle edges her whip. She uses it to take off Sebastian's hand in City of Glass.
  • Jessamine Lovelace from The Infernal Devices, edges her parasol, turning it into an effective weapon.

    Live-Action TV 
  • In one episode of Dad's Army 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.
  • In one 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 Midsomer Murders episode to decapitate a motorcycle rider.
    • And in a 1000 Ways to Die episode, "Golden Die-Angle", a drug enforcer is decapitated in the same way while riding an ATV.
  • An episode of Dark Angel had a police officer recount how some firemen got their throats slit by piano wire strung across doorways.
  • An episode of Angel had Angel and Spike pull this trick on a supposedly-unbeatable guardian.
  • Jerri relates a story on an episode of Strangers with Candy, in which a guy-wire slices Bongles the clown in two at the circus; leaving "two, small, dead clowns."
  • 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 Foyle's War, 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 Agents of S.H.I.E.L.D. 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 Kamen Rider Kabuto uses this as her signature weapon.
  • In Boardwalk Empire, 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.

    Tabletop Games 
  • 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 "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 Awesome, but Impractical 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).
  • The Eldar of Warhammer 40,000 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 is 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 still considered one of the more noble races in the setting, which says a lot about what kind of universe this is.
  • List of Things Mr. Welch Is No Longer Allowed to Do in an RPG (1001-1250) reminds us for a reason that
    1032. Monofilament does not automatically make the world a better place.
  • In TSR's short lived RPG 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.
  • 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.
  • Dungeons & Dragons
    • Crystal spiders from Dark Sun 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 Ravenloft spins webs of this stuff—usually right at neck level. Being so thin, they're near-invisible...
  • R. Talsorian Games' 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.
  • 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 Grimtooth's Traps (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).
  • Dragonstar has monofilament axes (and dwarven urgroshes).

    Video Games 
  • Kurenai, from Red Ninja End Of Honor uses a tetsugen, or an iron wire.
  • Sion's Etherite from Melty Blood 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 controlling their bodies.
  • Sima Yi uses "wired gloves" – gauntlets fitted with razor floss – as his primary weapon in Dynasty Warriors 6, ostensibly to symbolize his Puppet Master tendencies. He abandons them from the 7th game onwards, but 8 passes them on to his wife Zhang Chunhua.
  • Agent 47 from the 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.
  • Harp Note has this as one of her attacks. After binding you with her guitar strings, she riffs a few times. It hurts.
  • 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.
  • Marcy from Chrono Cross utilizes string-based attacks as her techs, for cutting, sending energy bursts through them and even shifting earth.
  • Kasuga from Sengoku Basara uses these as well as Kunai tied to the end.
  • Sonya Blade utilizes this as a fatality in Mortal Kombat 9.
  • Dishonored's Spring Razor's are basically spring-loaded razor wire landmines.

    Webcomics 
  • Reginald Jeeves (yes, you read that right) in And Shine Heaven Now: in fact, he was the one that taught Walter how to use them.
  • Butch from Chopping Block has some fun with wires on a ski slope.
  • Spoofed in this strip of Ctrl+Alt+Del where the author puts forth his theory of why headshots in Fallout3 tend to decapitate enemies.
  • Never Mind the Gap has living monomolecular wire. It was introduced cutting off a robot's metallic fingers.
  • Captain Tagon from Schlock Mercenary 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 (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 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 "eewww".
  • Subverted in this B Side Comic from Sluggy Freelance.

  • The SCP Foundation has SCP-183, is a creature made from invisibly thin monofilament fibers.
  • The Orion's Arm universe has 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 Worm, Skitter uses Clockblocker's power to make one of these suspended in air for her opponent to crash into.

  • The Simpsons had an episode where Snake (the convict guy) tried to kill Homer by setting up a fine wire across the road as Homer drove past in a Sports car. He only succeeded in cutting off Kirk Van Houten's arm.
    • Truth in Television, as he was using piano wire, which is strong enough that something hitting against it like Kirk's arm at that speed would be severed in a cutting fashion.

    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 The Troubles.
    • 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 channeling it 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 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 Truth in Television: 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, but just pull it by one side — and Off with His Head!!
  • Cheese cutters. They 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 - and lose control of it and� rrrrip. This can strip flesh to the bone - or even in some cases strip limb from body.
    • 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 aircraft carriers. They are inspected daily. Having one of them snap is a very bad thing.
    • During the filming of the unfinished 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 Texas 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 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 be flayed by moving 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. 'Dangerous as hell. — people die: onlookers, participants, people who are just in the wrong place at the wrong time will get their throats easily slit if a kite with strings like these passes by. This style of kite combat is actually fairly common all over the world, but specially popular in these two 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 the thick wires and kill the kite flyer b 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 even 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 The Kite Runner 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 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; application of proper force would let one slide through just about anything like a hot knife to butter.
  • The winch cable they use to launch gliders can be quite dangerous: a kilometer long cable moving at high speed, there are stories it cut a cow in two, unlucky enough to wander on the airfield. 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 man 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 during the drop. The most commonly seen mistake in movies is to make the length too short, choking the victim to death. However, a too-long rope can easily turn a hanging into a decapitation. This has 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 have you ever being cut by the edge of a paper sheet?. It's rare that it occurs (at least intentionally), but when it happens is quite painful. High-quality paper for color laser printers is the worst, as it has both rigidity and far thinner edges than photo 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 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 using wire. The silicon crystals are cut into wafers (for chip manufacturing) by using wire saw. It uses metal wire and a suspension of abrasives (diamond powder etc) in water. A bit like egg slicer (it cuts many wafers at once).
