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.

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, probably because Mon Lon was toying with Ranma at the time. He was actually about to go for the kill when Shampoo intervened.
- 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 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 A Certain Magical Index, Kaori Kanzaki uses this to simulate super fast sword strikes. Her old student Itsuwa can do it too, but she's not as skilled.
- 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.
- Lubbock's Imperial Arms makes use of this trope in Akame ga Kiru!. 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.
- Linna Yamazaki from Bubblegum Crisis has microfilament hair ribbons from her Hardsuit's helmet that can cut through enemies and weapons.
- 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.
- Subverted in Buck Godot: Zap Gun for Hire, an alien ninja threatens the chief of security with what he assumes is a mono-molecular garrote, but is really just floss.
- In Power Games, Shamal uses her Device's threads to decapitate a Mariage.
- 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.
- 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.
- An episode of NCIS had a killer who used a motorized garrote; just start the motor and the wire would tighten over whatever it was placed on. Yes, whatever—at one point she set the device on the handles of a pair of double doors in order to keep Gibbs in a room long enough to make her escape.
- 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 Razors are basically spring-loaded razor wire landmines.
- 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. He was using piano wire, which is strong enough that something like Kirk's arm hitting it at that speed would indeed be cleanly severed.
- 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 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 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 (which requires kinking the victim's windpipe), but just pull it by one side and Off with His Head!
- 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 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 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 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 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 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 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 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 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.
