%% One quote. Extras go on the quote tab.

A version of the SadisticChoice when a person is forced to make a terrible choice -- they need to remove one of their appendages in order to escape with their life. Sometimes a villain or NinetiesAntiHero imposes this choice as a punishment, but in other cases, a character is simply trapped.

Many animals will do this to escape traps in real life. Note that even if a person manages this, realistically they will bleed to death (which might be just what the villain has intended) in a few minutes unless they are able to close the wound, so [[DontTryThisAtHome only try this]] if you have a plan for doing that.

AmputationStopsSpread is similar but to stop poisoning or infection instead of escaping. Compare DisposableVehicleSection when similar thing happens with vehicles.

[[folder:Anime & Manga]]
* In the final episode of ''Manga/{{Berserk}}'', [[spoiler:Guts has to chisel off his own left hand, which is caught in a demon's jaws, with a broken sword in order to save his love Casca, who is in the middle of being raped by Femto, the demon lord that used to be their former captain Griffith. Though he ultimately fails to help her due to being dogpiled by demons mere moments after finally freeing himself, that doesn't make the moment any less {{Badass}}]]. What makes the scene even more badass is that [[spoiler: [[MajorInjuryUnderreaction Guts doesn't seem to be grunting in pain]]: more like in annoyance that any other time in the series, appendages are flying like confetti, but when ''he'' needs ''his'' arm detached '''right then and there'''...]]\\\
This proves to be rather fortuitous, though. He gains the ArmCannon after he heals, which has saved his life pretty much every single time he's clashed with dangerous foes. The ironic thing is that it was his left arm that was always the most protected throughout the series up until the Eclipse.
* In fourth ''LightNovel/{{Slayers}}'' novel, and in the corresponding scene in the ''Slayers: Revolution'' anime, fleeing villain Zuuma blocks Lina's Flare Lance spell with his ''remaining'' arm (having ''already lost one'' in the preceding fight) and manages to escape while ''completely armless''. Lina is fairly stunned. Leads to a quick conversation in another novel. Lina discovers Zuuma is back... and has all his arms. Gourry's response? [[spoiler:Shit.]]
* ''Manga/BattleAngelAlita'' does this a lot, although due to Alita being a full conversion cyborg the amputations or dismemberment are less than permanent.
* ''Manga/{{Bleach}}'':
** [[AloofBigBrother Byakuya]] is fighting a villain that can control Byakuya's limbs. Zommari first attempts to control Byakuya's left leg. Byakuya doesn't hesitate to sever the tendons and muscles of his own leg to render his limb useless. When Zommari tries to take advantage of the fact Byakuya's now stuck fighting him one-legged, he learns Byakuya's speed is still incredible but manages to take control of Byakuya's left hand and tries to strangle Byakuya with his own hand. Byakuya again doesn't hesitate and immediately severs the tendons and muscles in his left hand as well. Byakuya's then forced to finish the fight one-legged and one-armed.
** See also [[spoiler:Soifon]], who rather than [[spoiler:let her body be completely taken by Barragan's power to age her to a skeleton, has her lieutenant cut off her arm]]. Afterwards, [[CrowningMomentOfAwesome asskicking ensues]].
** [[spoiler:Hachi]] faces the same situation, but manages to turn things to his advantage by not just cutting off his arm, but [[spoiler:teleporting it inside Barragan, causing him to rot under his own power, killing him]].
* Inverted in ''RaveMaster.'' Shuda could have allowed Haru to save his life, but opted cut off the hand Haru was holding and fell to his [[NotQuiteDead not quite death.]]
* In ''TsubasaReservoirChronicle'' Kurogane chooses to [[spoiler: cut off his own arm in order to save Fai's life when they were trapped in the collapsing world of Ceres,]] making most [=KuroFai=] fangirls shriek "CANON!" and {{CLAMP}} snicker at their own evilness.
* Rin from ''{{Mnemosyne}}'' breaks her own wrists with such nonchalant indifference, it makes you wonder just how many handcuffs she escaped this way in her [[{{Immortality}} very, very long life]].
* ''OnePiece''
** Zoro is dead set to escape from a giant birthday cake ([[ItMakesSenseInContext long story]]) by cutting off his feet and then engaging the enemy. Luckily he's only about halfway through by the time [[BigDamnHeroes the cavalry arrives]].
*** Zoro likes this trope: his go-to solution for problems is "cut a limb off". Luckily when he's handcuffed to Usopp and suggests they do rock paper scissors to decide who cuts off their hand, Usopp is able to squash this idea before he begins. Zoro apparently thinks this is a good idea because [[{{Cloudcuckoolander}} he's sure their doctor can reattach the thing just fine.]]
** "Red Leg" Zeff on the other hand was forced to sever his own leg in order to avoid starving to death by eating it (manga) or in order to save a drowning Sanji (anime). {{Badass}} either way.
** "Chapter 0" shows that Gold Lion Shiki escaped the [[KryptoniteFactor sea stone]] shackles in [[TheAlcatraz Impel Down]] by cutting off his own feet, which he replaced with ''swords''.
** Similar to Zeff and Shiki, [[spoiler:Kyros]], who isn't a Devil Fruit user, cut off his leg, which was shackled by a sea stone shackle, to save [[spoiler:King Riku]] from [[spoiler:Donquixote Deflamingo]]. Unfortunately, [[spoiler:Sugar transformed him into a toy before Kyros could save the king]].
* ''Manga/{{Naruto}}''
** During Orochimaru's initial attack on Konoha, [[spoiler: He ends up fighting the Hokage, who as a desperation tactic attempts a technique that will draw both of their souls into a demon's stomach, there to [[SealedEvilInADuel continue fighting forever]]. While Orochimaru's spiritual arms are in the demon's mouth, he uses his tongue to wield a sword and cut them off, leaving the limbs paralyzed.]]
** [[spoiler:The Fourth Raikage attacks Sasuke]] while he is being protected by extremely hot [[spoiler:black]] flames, and is forced to sacrifice his arm to prevent the rest of his body from being burned up.
** Practically the same happens later to [[spoiler:Tobi]]: his arm is infected by TheVirus an enemy spreads by touch so he (non-chalantly) snapped his own arm off, then he ''[[GrievousHarmWithABody punt kicks it into his enemy's face]]''. We just found out that [[spoiler:Tobi was so nonchalant about losing his arm because he can grow or attach a new one as needed... and, unless it's a translation error, he can switch out ''his eyes'' too]].
* In ''LightNovel/{{Baccano}}'' the... [[SociopathicHero helper to the heroes]], Claire, forces the villain Ladd into one of these to save his bride, Lua, to preserve his vow that no one will kill her but Ladd himself. [[spoiler: Basically, Claire put a noose around Lua's neck while the trio stood on top of a moving train, and attached the other end of the rope to a stationary post not connected to the train, thus forcing Ladd to either abandon his fight with Claire and save her or continue the fight and let his fiance be decapitated. Hardly a choice at all, since Claire had picked up on just ''how much'' Ladd's vow to kill Lua himself was worth to him.]]
* Prior to when ''Manga/FullmetalAlchemist'' begins, Ed sacrificed his arm to seal Al's soul in a nearby suit of armor during their botched human transmutation attempt.
** And even before that (in-series time), [[FanNickname Scarbro]] transmuted his right arm to Scar to keep him from dying.
** Later on, [[spoiler:Lan Fan cuts off her (at this point already useless) arm to distract King Bradley from following her and Ling.]] Of course, given the existence of auto-mail, this isn't quite as life-changing as it might be, but it's still an extremely brave choice to make.
** In the [[Anime/FullmetalAlchemist 2003 anime version]], Kimblee transmutes Scar's left arm into a bomb. Rather than wait for it to detonate, Scar destroys the arm completely and takes advantage of Kimblee's shock to kill him. Soon afterward he sacrifices his remaining arm to save Al from suffering the same fate, resulting in a few [[{{Narm}} unintentionally humorous]] scenes of an armless man running around Lior luring in Ametris soldiers.
* In a chapter of ''{{Claymore}}'' [[spoiler: Claire is obliged to make this decision ''for'' her fellow renegade Uma when the NighInvulnerable Dolf got ahold of the latter's leg]].
* In the first ''Anime/TengenToppaGurrenLagann'' CompilationMovie Yoko and Adiane's DesignatedGirlFight ends with Yoko pinning down Adiane's [[PettingZooPeople scorpion tail]] that she used to deflect bullet, but before she can get the finishing shot in Adiane cuts her own tail off to escape.
* In ''Anime/LeChevalierDEon'', [[spoiler:Durand]] prevents Mr. Whitehead from taking control of him via the Psalms by cutting off his own arm before the effect of the Psalms could spread any farther than that.
* In ''{{Kaiji}}'', the title character plays a game called E-Card in which he is given the choice of wagering his ear or his eye. He chooses the ear, to which a device is attached that contains a drill bit which moves closer to his eardrum with each hand he loses. The device also [[spoiler:sends vital signs to his opponent which tip him off to when Kaiji is planning to play an important card]], and once he realizes this, he [[spoiler: ''cuts off his entire ear'']] and continues the game. And ''immediately after that'', he wagers four of his fingers in a lot-drawing game which he [[spoiler:loses]].
* [[LadyOfWar Erza]] of ''Manga/FairyTail'' was prepared to amputate her arm to stop the poison from a snakebite spreading through her body, but was stopped on the premise that [[TokenMiniMoe Wendy]] had healing magic. Unfortunately, she had been kidnapped by the members of [[QuirkyMinibossSquad Orachion Seis]] [[spoiler:with the intent of having her resurrect Jellal]], so it was a race against time for the rest of the alliance to save Erza's life.
* In the manga ''Torikago Gakyuu'', Mikage, after he's kidnapped by [[spoiler: [[EvilTwin Yuikai]]]], is given the [[SadisticChoice choice]] of having his ears cut off and becoming [[spoiler:Yuikai]]'s slave or being pushed out the window of a secret room in the school's clock tower (tied up, no less). [[WhatAnIdiot He chooses the latter.]] Fortunately, [[spoiler:Yukan]] arrives just in time to catch him, but Mikage still gets a good deal of [[UnwillingSuspension discomfort]] from his decision.
* ''LightNovel/HighSchoolDXD'' has Azazel cutting off his left arm when Katrea Leviathan ensnared his arm to kill both him and her when she was about to self-destruct. He regrows it later anyway.
* In ''LightNovel/ACertainMagicalIndex'', Acqua of the Back completely dominates [[TheHero Touma Kamijou]] in a CurbStompBattle, then tells him if he cuts of his right arm (and thus, gets rid of [[AntiMagic Imagine Breaker]]) in a day, then Acqua will spare his life. Of course, Touma refuses to do this and instead beats him in the rematch.
[[/folder]]

[[folder:Comic Books]]
* In Franchise/TheDCU, ComicBook/GreenArrow [[spoiler:got his arm stuck in a bomb and]] was offered a choice between losing his arm (meaning he could never use a bow again) or dying. He chose to die. (Don't worry. He got better later.)
** Within the continuity of ''ComicBook/TheDarkKnightReturns'', he apparently makes the other decision and has learned to pull his bow with his teeth.
* In ''ComicBook/{{Watchmen}}'', crazy AntiHero Rorschach tracks down a kidnapper who had killed a young girl, handcuffs him to a furnace, and sets his house on fire with him inside, leaving him with a saw. He tells the kidnapper not to bother trying to cut through the handcuffs since he wouldn't be able to make it in time, and then he stands outside, watching to see if the guy manages to escape. He doesn't. They changed this in [[Film/{{Watchmen}} the movie]] because they were worried that people would [[SeinfeldIsUnfunny be reminded too much of]] ''Franchise/{{Saw}}.'' Instead Rorschach simply cleaves his head open, which is the same thing he just did to the man's dog ("Men get arrested. Dogs get put down.")
* In an issue of Marvel's ''[[ComicBook/AvengersTheInitiative The Initiative]]'', trainee superhero Komodo's legs are injected with poison, which will kill her when it reaches her heart. Her teammate Hardball decides that the best way to deal with this under the current dire circumstances is to amputate the legs. Komodo can regenerate, of course, but this still triggers a phobic reaction, as her civilian form lost her legs as well.
* Another Marvel example: in an issue of ''IronMan: Director of Shield'', Tony Stark cuts half of his foot off with a laser in order to remove a power-suppressing anklet so that he can access Extremis and beat the Mandarin.
* In ''ComicBook/TheMetabarons'' series, Aghnar (the second metabaron) has implanted a lot of miniature bombs in his body and set them to go off if he is mortally wounded. When he faces off against a beast impervious to all his attacks, he shoves his arm down its throat and lets it get bitten off. The bombs in his lost arm then makes the creature collapse into a small sphere.
* Franchise/{{Batman}} foe the [=KGBeast=] cut off his own arm with a fireaxe after Batman snared it in a loop of cable and and was holding him pinned until the police arrived. Since the cable was too tough to cut with an axe...
* ''ComicBook/TheWalkingDead'' Several times. Most notably, the character Dale is bitten, and needs his leg amputated. Also happens earlier in the series with Allan, however, the amputation doesn't save him.
* In ''WebComic/BiteMe'', the gang faces off against a magical mechanical monstrosity. At this point, cowardly main character Hunter is the most useless member of the group, since while his TrueCompanions Chuck, Andrew, and Haruka have flame-spewing gloves, earthquake boots, and spinning guillotine blades, respectively, he cannot even lift the massive sword he was given (nor does he believe it's sentient, which it is, and it thinks he's a dumbass). After his entire team is slaughtered by this monster, in his first act of heroism and a CrowningMomentOfAwesome, Hunter plunges his hand in the monster's mouth to grab the heart-shaped artifact giving it life. The creature promptly bites his hand off, but thanks to his unexpected distraction both sides lived to fight another day. Naturally, this event kicks off his [[TookALevelInBadass Taking a Level In Badass]].
* In a variant, Two-Edge from ''ElfQuest'' has his feet trapped in solid stone by the rock-shaper Ekuar, whom he's kidnapped. He somehow gets free, leaving the empty, foot-shaped gaps drenched in his blood, but precisely how much of his feet he'd also left behind isn't clear.
* In the comic book backstory for Lieutenant Jean Rasczak from ''Franchise/StarshipTroopers'', the young marine is the only soldier survivor of the first encounter with the bugs. As he hauls ass back into the dropship, one of the Warrior Bugs traps his arm with its mandibles and attempts to pull him back out. He orders the terrified civilian survivor to seal the door -- doing so severs his arm but saves his life.
* In the ''PlanetHulk'' storyline, Miek chops off his own arm to avoid getting pinned down during a fight with another alien monster. Being a giant insect, Miek has arms to spare, but it doesn't grow back.
* In ''{{Transmetropolitan}}'', Spider decides that chewing his arm off at the shoulder is the obvious means of escape when he [[spoiler: wakes up in bed next to Yelena.]]
* In ''{{ComicBook/Hitman}}'', Hakan gets bit by a zombie penguin and immediately cuts his hand off to avoid infection. Subverted when he later learns that it wasn't infectious.
* Invoked for laughs in ''DeCapeEtDeCrocs'', where Armand, a [[FunnyAnimal fox]], waking up in jail, briefly freaks out and attempts to gnaw his leg, "as any self-respecting fox should do".

[[folder:Films -- Animation]]
* In the animated ''{{Transformers}}'' movie, Starscream's foot gets caught in a closing gate during the Autobot City attack. He blasts his foot to get free (although what we see damaged is his lower shin). He's intact later in the movie -- being a robot, and everything.
[[/folder]]

[[folder:Films -- Live-Action]]
* The probable TropeCodifier and page quote provider: ''Film/MadMax'' ends with Max handcuffing the last gang member to the car whose gas tank he set up to explode before giving him the saw and said line. It's particularly cruel because if you watch the movie closely you'll notice that it doesn't matter which choice the cuffed bad guy makes, there isn't time for him to do either: From speech to explosion is about 3 minutes tops. That said, it could be just [[MagicCountdown movie time]]--not like it even matters, he'd bled to death before he could possibly find anyone to treat the wound.
* ''Franchise/{{Saw}}''
** The [[Film/SawI first movie]] has two people chained to pipes in a SealedRoomInTheMiddleOfNowhere. The only visible way out is a rusty hacksaw too weak to cut through the chains, but sharp enough to cut through their feet. [[spoiler:Gordon cuts off his own foot, and crawls out of the room to get help. He isn't seen for six movies, but revealed to have survived in the last one.]] Even as Jigsaw's traps get more elaborate in the sequels, they generally come down to "How much pain are you willing to go through to save your life?"
** ''Film/SawVI'' opens with two people in cages who are told that they must remove "a pound of flesh" and deposit it on a scale. The first to do so survives. The fat man of the two begins cutting off chunks of his stomach. The skinny girl cuts off her arm...[[spoiler: and wins.]]
* In the 2007 film ''Film/{{Beowulf}}'', during the fight with the dragon, [[spoiler:the title character ends up severing his arm to get himself in a better position to attack]].
** However, that isn't a very straight example, since he didn't do it for survival, [[spoiler: but to kill the dragon as it was threatening people he loved. By the time he severes his arm, it become clear that he has no intention of surviving the fight.]]
* The opening of ''Film/ScaryMovie 4'' parodies the ''Saw'' example with Shaquille O'Neil and Dr. Phil about to be killed by nerve gas. After being suckered into cutting off his own leg, Phil realizes it's the wrong one and they die anyway.
* Done "backwards" in ''Film/{{Se7en}}'', where for the Pride murder, the killer cuts off a fashion model's nose and then leaves her locked up with a phone and a bottle of sleeping pills, so she can decide whether to call the police and survive (with a deformed face) or take the pills and kill herself. She kills herself.
* ''Franchise/EvilDead'':
** Ash in ''Film/EvilDead2'' has to cut off his own hand, possessed by evil, with his chainsaw. Unfortunately, that is ''not'' enough for the hand to stop attacking him.
-->'''Ash:''' Who's laughing now? Who's... LAUGHING... NOW!?
** [[Film/EvilDead2013 The 2013 remake]] does it rather differently. The demonic abomination flips a jeep onto the Ash {{expy}} [[spoiler:(Mia)]], whose hand get pinned under it. With a chainsaw lying just out of reach and the abomination steadily approaching, the trapped hand must be ''pulled off''. There's also a scene where Natalie cuts off her own infected arm to try to keep the demonic corruption from spreading. [[spoiler: It doesn't work, possibly because the demon kissed her forcing its blood down her throat.]]
* A particularly complicated example from the Hongkong comic book movie ''Film/TheStormRiders''. Brooding BadAss Bujing Yun uses a skill very much like waterbending from ''WesternAnimation/AvatarTheLastAirbender'', and carries his dead lover to a mausoleum located conveniently in the desert, where the BigBad, played by Sonny Chiba, lies in wait. With the arid climate crippling his powers Yun is beaten by the Big Bad's earthbending-esque skills, and Yun even gets the bones of his left arm shattered in a ShoutOut to Chiba's ''Street Fighter'' movies. What does Yun do? Promptly TEAR OFF HIS LEFT ARM, using the torrent of blood to pull off a bloodbending strike on the Big Bad, and secure his escape. [[http://www.youtube.com/watch?v=JDps1d8Ydsw&feature=related See the whole thing here]]. Warning: CrowningMomentOfAwesome.
* In ''Film/{{Evolution}}'', Dr. Block finds himself host to an alien fly that is burrowing into his leg. He refuses to let doctors cut off the leg in question until he learns that it's headed for his testicles. ([[spoiler:Ultimately, they pull it out of his rectum instead.]])
* In the film version of ''Film/{{Hannibal}}'', Starling handcuffs both Lecter's wrist and hers to a fridge to prevent him from escaping. Lecter grabs up a cleaver, remarks that this is going to hurt, and hacks through [[spoiler:his own]] wrist, allowing him to evade capture.
* In ''Film/RepoMen'', Remy and his multiple-recipient girlfriend must scan the barcodes of their implanted artiforgs to remove themselves from the To-Be-Retrieved list. The scanners won't work through flesh, and both of them have ''internal'' artiforgs, [[TheyWouldCutYouUp so...]]
* In ''Film/{{Slugs}}'', Harold cuts off his hand with an axe after he puts it in a glove with a killer slug inside it. Kinda over-the-top, but so is the following explosion from a single gas canister that destroys his whole house.
* ''Franchise/{{Terminator}}''
** In ''Film/TerminatorSalvation'', a T-600 sacrifices its foot to free itself from a rope trap.
** And in ''Film/Terminator2JudgmentDay'', the T-800 has his arm trapped and crushed between two gears, and pries it off above the elbow with a metal bar so he can defend John and Sarah Connor from the murderous T-1000.
* In ''Film/DeadSnow'', one of the characters gets bitten by a zombie, and, to save himself from zombification, cuts the arm off and cauterizes the wound. Unluckily for him, a zombie pops up with a bite-based GroinAttack shortly thereafter.
* ''Film/TheBoondockSaints'': The titular heroes, Connor and Murphy [=MacManus=], have been captured by the Mafia and left handcuffed to chairs awaiting torture and execution. When their captors leave the room, Connor breaks Murphy's hand to allow him to slip the cuffs and get the drop on the goons when they return.
* ''Film/OneHundredAndTwentySevenHours'' is based on the true story of mountain climber Aron Ralston. See it in the Real Life section.
* In ''Film/{{Buried}}'', [[spoiler: Paul Conroy]] is forced to [[spoiler: sever his finger on video,]] or else the terrorists keeping him hostage would [[spoiler: kill his wife and son.]]
* In a ''Franchise/{{Gamera}}'' film, the heroic turtle finds his arm pinned to a building by one of his foe's spiny tenticles. His response? To blow his own arm off with a fireball, use said fire breath to light his stump on fire, and then plunge this bloody, flaming mess into his foe's chest(!). This is also undoubtedly an AwesomeMoment for the big guy.
* In ''Film/PiratesOfTheCaribbeanOnStrangerTides'', Barbossa reveals that he cut off his leg to avoid being drowned by a voodoo-controlled rope.
* One mook resorts to this in ''Film/PhantasmII'' after his hand is pinned to the wall by one of the BigBad's flying Sentinel spheres.
* In ''Film/CabinFever 2'', the hero, having already had his prom ruined by a schoolwide outbreak of necrotizing fasciitis (it's complicated), gets some infected blood on his hand and so, to prevent himself from getting infected, goes to his school's shop classroom and cuts his hand off with a chop saw. [[spoiler:It doesn't work.]]
* ''Film/TheFinal'': The football star and the cheerleader are forced to cut off each other's fingers in a SadisticChoice and are then left to live with the consequences.
* ''Film/ThePrestige'' It's more a case of Life Or Livelihood Decision, but the decision by Borden to [[spoiler:cut off his twin's finger so that they would have matching disfigurements]].
* Subverted in ''Film/{{District 9}}''. An infection has gotten hold of Wikus, the first effects of it showing up in one of his arms. Distraught, he takes an axe with the intent of cutting off the limb, presumably to stop it from spreading any further. It looks like he's going to do it, but [[FinGore he cuts off a thumb first]] and the pain prevents him from chopping off anything else. Wikus eventually loses his [[spoiler:human]] life, but it's doubtful cutting off the entire arm would have saved him anyway.
* Gerry had to cut off the female Israeli soldier Segen's hand since she was bitten by a zombie in ''Film/WorldWarZ''. Her life was saved as a result.
* In ''Film/RoboCop2014'', Murphy shoots off one of his arms when it's pinned under an ED-209 and two more are bearing down on him.
* ''Film/BattleBeyondTheStars'' (1980). [[BigBad Sador]] finds out almost too late that [[OrganAutonomy a Nestor hand can be controlled by the]] Nestor HiveMind even after it's been cut off and [[MixAndMatchMan implanted onto his own arm]]. His TortureTechnician is able to stop Sador from [[EvilHand cutting his own throat]] by quickly chainsawing off the limb.

[[folder:Literature]]
* This is used by Rachel of the ''Literature/{{Animorphs}}'' in ''The Solution'', Book #22. She's in rat morph and has to chew through her own tail [[spoiler:in order to escape being locked in the cage with SixthRangerTraitor David.]]
* This is how Maedhros lost his right hand in ''Literature/TheSilmarillion''. He was captured by Morgoth and hung off a cliff by a metal shackle around his wrist, a very painful experience. When his cousin Fingon comes to rescue him Maedhros begs for a MercyKill because Fingon can't break the shackle. Fingon opts to free him by amputating hand above the shackle instead, since he ''can'' cut that.
* ''Literature/{{Dune}}'' has a form of this in the test through which Reverend Mother Mohiam puts Paul. The Bene Gesserit nerve induction box inflicts an enormous amount of pain on the order of third-degree burns, while the gom jabbar ("High-handed enemy", which she will plunge into his throat if he pulls his hand out) will kill almost instantly.
-->'''Mohiam:''' You've heard of animals chewing off a leg to escape a trap? There's an animal kind of trick. A human would remain in in the trap, endure the pain, feigning death that he might kill the trapper and remove a threat to his kind.\\
'''Paul:''' Why are you doing this?\\
'''Mohiam:''' To see if you're human.
* At the beginning of ''Literature/SwanSong'', a colonel trapped in a bunker orders the soldier and civilian boy who are trying to free him to first cut off his hand and then cauterize the flesh with heated instruments he had them prepare first.
* Also in ''[[Literature/TheFionavarTapestry The Summer Tree]]'', the immortal Big Bad has freed itself from confinement by losing an arm, but due to the nature of his immortality it cannot heal and just drips blood and ooze continually.
* In ''TheWarlordChronicles'', Derfel faces a variant where, due to complicated circumstances that have grown up over the course of decades, his best hope of saving his wife from a KnightTemplar sorceress is to cut off his own hand. He goes through with it and manages to save his wife.
* Played straight and later subverted in ''Literature/TheClone'' by Kate Wilhelm and Theodore L. Thomas when the titular synthetic organism gets on two different characters' arms. The first time, it works; they lop off the guy's half-absorbed arm and he survives. The next time, though, the clone adapts and gets into the second guy's body under the skin and [[BodyHorror eats him from the inside-out]], which they only discover ''after'' they've already cut the arm off.
* In Creator/StephenKing's ''TheStand'', the last survivor of a city steps on a rusty nail, and gets gangrene. Because all the doctors are dead (and the hospitals are ransacked), he can't figure out how to treat it. He tries to saw off his foot, but faints from the pain and bleeds to death.
** Also appears in the short story "Survivor Type."
** And in the short story "The Mangler". The victim has his hand caught by eponymous machine and is slowly pulled in. Another man discovers that machine cannot be turned off, so he lops victim's arm off with a fireaxe.
* Stephen King loves this one. In ''GeraldsGame'', a woman is ChainedToABed in the middle of nowhere when she manages to semi-accidentally kill her husband. A particular version of this trope is how she eventually manages to free herself -- [[spoiler:she breaks a glass and effectively scalps her hand, pulling the resulting bloody mess through the cuff.]] Well it ''is'' Stephen King.
* In ''The Druid of Literature/{{Shannara}}'' by Terry Brooks, Walker Boh's right arm is petrified, and he has to smash it off to prevent the rest of his body from being petrified as well.
* Happens twice in the ''Literature/AgeOfFire'' series. [[spoiler: First, in ''Dragon Champion'', [=AuRon=] tears off most of his tail after the end is bitten by another dragon with lethal venom, to prevent it from killing him. Later, in ''Dragon Strike'', Nilrasha chews off her own ''wing'', pinned under rubble, to escape being killed while trapped.]]
* Not his own limb, but possibly worse: Hawk from Simon Green's Haven novels once had to sever the foot of a (mercifully unconscious) little girl, to free her from the rubble of a collapsed building. [[spoiler:Subverted in that, at the book's end, he meets the girl and her mother, and learns that the local wizards have successfully re-attached the child's foot.]]
* In the ''TabletopGame/{{Ravenloft}}'' novel ''Death Of A Darklord'', an elf's lost arm is regenerated by the powers of a young sorceress. Unfortunately, the sorceress has been tapping into dark forces to heal people, and when the bandaged arm is unwrapped, it's become a grotesque wormy tentacle that attacks everyone in sight. The horrified elf immediately begs his companions to cut it off. Possibly a subversion, as the elf may not even have survived the amputation.
* In ''Discworld/{{Pyramids}}'' from the ''Literature/{{Discworld}}'' novels, Pharoah Pteppic shakes a stonemason's hand in an attempt to be friendly. His ideas of kingship are a little different from those in his country, and is shocked when the man backs away screaming and clutching his arm. It's explained to him that for the man to use his hand would be a blasphemy against the divine pharoah, which is probably punishable by death. The man's hand is amputated by the priests. When Pteppic protests this the high priest tells him that if he hadn't been restrained the man would have done it himself, with his chisel.
* ''Mindstar Rising'' by Creator/PeterFHamilton. The main character and his friend mangle each others' hands so that they can slip them through handcuffs; describing the whole sequence of events, in [[{{Squick}} squicky]] detail, takes several pages. The hero can use his neural implants to minimize the pain, but not his friend.
* In a later volume of the ''Literature/VorkosiganSaga'', Miles (brittle-boned from before birth) is chained up by his enemies; he recalls that on one spectacularly unpleasant occasion, he broke the bones in his hand in order to get out of cuffs; unfortunately for him, ''since'' that time he has had nearly all of his bones replaced with synthetic ones, even less breakable than normal.
* ''TheSwordOfTruth'' features a sorceress named Adie who had to cut off her leg after being attacked by a magic resistant armadillo/leech hybrid. Subverted later, when she gets infected with a magical disease. When she asks a wizard to cut the infected limb off, he explains the disease is already all over her body.
* In L. Jagi Lamplighter's ''[[ProsperosDaughter Prospero Lost]]'', Miranda recounts how they were driven from Milan by sorceresses -- one of whom set serpents on their soldiers. One soldier chopped off his leg trying to free himself from the snake.
* In ''The President's Daughter'' series by Ellen Emerson White, a kidnapped Meg faces this problem in the book ''Long Live The Queen'' when she's handcuffed in the middle of nowhere. She ends up smashing her own hand to bits with a rock in order to escape. Did I mention that she's already had her knee smashed before this as well?
* In Max Barry's ''MachineMan'', Dr. Charles Neumann is forced to sever his left arm at the shoulder. It had already been mostly torn off, and it was either that or bleed to death.
* In ''Peer Gynt'', an individual chopped off one of his fingers not to be recruited.
* ''ConanTheBarbarian'' attempts a heroic version of this to crawl to the rescue in ''Red Nails''. He is prevented when he realises he dropped his sword when the trap closed on his leg and it is now out of reach.
* Stephen Maturin is forced to amputate many limbs in the ''Literature/AubreyMaturin'' books. At the time this was generally the only option for serious limb injuries, especially with the risk of gangrene. Unlike many surgeons though, Stephen did his best to preserve limbs, only amputating as a last resort. Jack Aubrey suffers a serious arm injury during the battle between the USS Constitution and HMS Java, and his arm is only saved due to Stephens skill and patience. Stephen is also forced to apply this trope to himself when he suffers frost bite in his toes whilst crossing the Andes, informing the crew (during dinner) that he "removed the peccant members" with a chisel.
* ''[[Literature/CiaphasCain The Greater Good]]'': When a Tyranid spore's tentacle gets hold of Cain's leg, he can't get a clear shot at the tentacle ... but has a very clear shot at his leg. He orders Jurgen to get the medical kit and revs up his chainsword. And then the [[SpaceMarine Reclaimers]] play BigDamnHeroes and kill the spore just in time.

* ''GreysAnatomy'': After an injury to her leg (from a plane crash) becomes seriously infected, Arizona Robbins asks her wife Callie not to let them cut it off, no matter what. However, when the infection takes a turn for the worse, Callie is forced to go back on her word and makes the call to have it amputated.
* ''Series/AgentsOfSHIELD'':
** In the Season 2 premiere, [[spoiler:Hartley]] touches the Obelisk and her hand begins to turn to stone. [[spoiler:Hunter]] manages to cut it off to save her life, but to no avail.
** In the Season 2 episode "The Writing on the Wall", Ward dislocates his thumb to escape from a pair of handcuffs.
** In the Season 2 finale, ''SOS'', [[spoiler:Director Coulson catches an impure Terrigen Crystal just before it shatters on the ground and its mist kills every human in the room. The impure crystal begins to turn his hand to stone, and it is immediately cut off by Mack using a fire ax. It works this time.]]
* Similarly to the ''Agents of S.H.I.E.L.D.''example above, in the TV series ''Series/{{Hannibal}}'' (but predating it by a year and a few months), the [[spoiler:fake Chesapeke]] ripper escapes police custody by dislocating his thumb to escape his handcuffs.
** In a later episode, [[spoiler:Will]] remembers this and uses it to escape police custody in a similar way, albeit non-lethally.
* ''Series/{{CSI}}''
** One episode begins with finding a dead woman who was missing a hand. They eventually find that she had bitten it off to escape from a psycho's basement.
** In "Consumed", it looks like a cannibalistic serial killer chewed through his own wrist in order to escape, leaving his hand handcuffed to the inside of a car. [[spoiler:It was actually staged to allow the killer to exaggerate his mystique]].
** ''Series/CSINewYork'' does this too, except they find the hand before they find the body. Turns out the man, who was an ex-con, had been lured to an abandoned church by his old partner in crime, knocked out and chained to the church wall. He died from a mix of blood loss (from biting off his hand), starvation and hypothermia. According to the killer, he was going to let him out eventually and wasn't at all expecting him to bite off his own hand.
* In the 3rd season finale of ''Series/TwentyFour'', the final canister of the virus ends up being handcuffed to Chase. With only seconds before the timer is set to go off, he gives Jack Bauer permission to chop his hand off with an ax so the canister can be removed and tossed in an airtight refrigerator to keep it from spreading.
* MagnificentBastard Lucas Buck does a copy of the ''MadMax'' situation to a bad guy in the ''AmericanGothic'' episode "The Strong Arm of the Law." Except the man is handcuffed to his brother, and it's his limb he has to cut off.
* In ''Series/StargateSG1'', [=RepliCarter=] attempts to flee through the Stargate, but Teal'c holds her by the arm. Being a robot, it's a simple matter to detach it, though she presumably does not feel any pain. In addition, next time we see her, she has regrown it.
* A variant occurs in ''Series/StargateUniverse'', where Eli is forced to stick his arm through the event horizon of the Stargate, risking a potential PortalCut if it deactivates, in order to keep it open and prevent the ship from jumping to FTL. If he doesn't, the team carrying the mineral needed to fix the oxygen recyclers won't make it back and they will ''all'' die of asphyxiation. Luckily, neither the team or his limb are lost.
* [[CrossesTheLineTwice Played for laughs]] in a sketch on ''KidsInTheHall''. The sketch revolves around stereotypical French fur trappers who canoe around an office, trapping people and killing them for their suits. When one of the people chews off their own leg to escape a trap:
-->'''Francois:''' Shall we go after him, Jacques?\\
'''Jacques:''' Let that one go, Francois. He has spirit. Someday he may be vice president!
* Variant in ''Series/{{Chuck}}'', when the eponymous hero is ChainedToABed: he probably wouldn't have been killed, but the bad guys would no doubt have done some very nasty stuff to him. Casey tells him that handcuffs are a cinch to get out of -- all you have to do is snap ''one little bone'' in your thumb -- but Chuck manages to [[TakeAThirdOption get hold of the key instead]]. [[ChekhovsSkill Later in the episode]] Casey's forced to follow his own advice.
* In a round of the dating game on ''WhoseLineIsItAnyway'' (US), Wayne Brady's character is a frat boy who has woken up chained to an ugly woman (Colin Mochrie). He attempts to gnaw his arm off to escape, but fails, and is dragged all over the studio by Colin (whose character is an incompetent 1930s gangster).
* In the ''Series/{{House}}'' season 6 finale, the victim of the week gets her leg crushed under a building. [[spoiler: To avoid crush syndrome (even though by then, it would have set in...), House and Cuddy decide to hack her leg off using a scalpel and a crude anesthetic. She was very hesitant to let them, and House [[YouRemindMeOfX agreed with her]]. She [[MauveShirt dies of a fat embolism]] on the way to the ER.]]
* ''Series/TheWalkingDead'':
** In the first season, the zombies arrive at the rooftop where Merle Dixon has been handcuffed and abandoned by the rest of the group, and he escapes by amputating his hand with a hacksaw from the bag of tools that was conveniently dropped next to him.
** In season 3 this happens to [[spoiler: Hershel]], who is bitten on the leg, forcing the group to amputate it in an attempt to save him. [[spoiler: It actually works.]]
* In season 2 of ''PrisonBreak'' T-Bag was forced to re-sever his reattached hand to evade recapture by the police after he was left tied to a radiator by Bellick and a colleague, who were after the D.B. Cooper money he had taken.
* ''Series/TheXFiles'':
** The inhabitants of an isolated Russian village use amputation to render their citizens [[spoiler: and Krycek]] unsuitable as test subjects for the Syndicate's black oil experiments.
** {{Downplayed}} in "Leonard Betts". It's Freedom or Finger Decision in this episode. Betts is handcuffed to a car handle and tears off his [[{{Fingore}} own thumb]] in order to escape. His choice is made easier as he knows the finger will grow again due to his accelerated HealingFactor.
* On ''Series/TeenWolf'', Kate Argent shoots Derek in the arm with a wolf's bane bullet which, since he's a werewolf, causes an infection that will kill him if it reaches his heart. He is literally seconds away from forcing Stiles to help him cut off his arm, when Scott [[JustInTime arrives]] with the antidote.
* In a Season 3 episode of ''Series/{{Nikita}}'', Nikita and [[spoiler: Michael]] are pursing [[BigBad Amanda]] in a car chase that results in a crash with [[spoiler: Michael]]'s arm pinned and the car on fire and about to [[EveryCarIsAPinto explode]]. Unwilling to leave [[spoiler: Michael]] to die, Nikita is forced to cut [[spoiler: his]] hand off to drag [[spoiler: him]] to safety just in time.
* ''Series/RedDwarf'': In order to save Dave's life from the Epideme virus, they get him to agree that they'll amputate his LEFT arm.
* ''Series/DoctorWho'': In the Series 7 episode "The Angels Take Manhattan", the Doctor reads in a book written from his future that River breaks her hand. It turns out that she has to do that to escape from a Weeping Angel. This has a fair amount of plot relevance. [[spoiler:The Doctor also infers from the chapter names that Rory dies. He insists that River not break her hand to escape from the Angel. The fact that she did is a bad sign since it means that the events of the book are going ahead as written. And, indeed, Rory does die. He gets better.]]

[[folder:Myths & Religion]]
* NorseMythology: The gods are finding Giant Wolf Fenrir hard to control and thus decide to bind him, claiming to the enormous wolf that it is a game. As a gesture of good faith, the god Tyr puts his hand in the wolf's mouth and when Fenrir realizes he cannot escape, he bites off Tyr's hand. The story definitely shows the god as honorable and brave, given that Odin, Thor, and others certainly didn't volunteer their limbs.
* There is a Native Alaskan totem depicting a boy with his hand in the mouth of a monster. It's a giant oyster that caught him while he was fishing. According to the story, he was given a choice between losing the hand (and his chance to be a hunter) and death. He chose death.
* [[Literature/TheBible "If your right hand causes you to sin, cut it off and throw it away. It is much better for you to lose one of your limbs than to have your whole body go off to hell."]]

* ''TabletopGame/{{Shadowrun}}'''s mega-{{Badass}} Kid Stealth was given cement overshoes and tossed into Puget Sound by his enemies. An implanted air tank kept him from drowning long enough to tie ligatures around both legs, then blow them off at the knee with plastic explosives. (He got better... legs, that is.)
* ''TabletopGame/{{Deadlands}}'': "Hogleg" Dunstan, the sheriff of Lost Angels, was handcuffed to the bed inside his own jail cell and the office set on fire around him. He escaped by cutting off his right hand.

[[folder:Theater]]
* Shakespeare uses this one in ''Theatre/TitusAndronicus,'' albeit with a twist: the villainous Aaron tells the title character that his sons, condemned to death on false charges, will be spared execution if Titus cuts off his hand. Titus does so (after arguing with his brother and son over who gets to have their hand removed), but Aaron is just screwing with him and his sons are executed anyway. (This leads to the fabulous stage direction ''Enter Messenger with two heads and a hand.'')
* In Hanoch Levin's ''Everyone Wants to Live'', Poznavokha tells her husband Pozna, whom she caught cheating on her with a travelling actress, to choose: either he gets castrated and she agrees as planned to [[ItMakesSenseInContext allow the Grim Reaper to take her life in exchange for Pozna's]], or keep his jewels till he dies by the Reaper's hand. He chooses the former. It is not pretty. [[spoiler:Then, when the time comes, she [[SubvertedTrope decides not to go through with it]], having [[DistractedByTheSexy felt the undertaker's muscular body]]...]]

* Rudy from ''[[VideoGame/WildArms1 Wild ARMs]]'' cuts off his own arm to free himself from the grappling hook-like thing which the demon Ziekfried has ensnared him with, when he realizes his sword can't cut through the cord. In the remake, wherein he doesn't use a knife, he uses his gun to blow his arm off, instead.
* ''VideoGame/DeadSpaceExtraction'', [[spoiler: just after the final boss, the main character gets impaled to the ground (well, to the hull of the ''Ishimura''), and has to cut his arm off to break free. And it isn't a CutScene. The dumb part of this example is the fact that this happened in vacuum... even if he remained conscious after cutting his arm off, his suit would have depressurized long before he made it to an airlock]].
* In ''VideoGame/MetalGearSolid 4'', [[spoiler: Raiden gets trapped under rubble during the escape from Shadow Moses Island]] and has to cut off his own arm to escape. Although [[spoiler: by that point, Raiden is a human head and a spine attached to a robotic body, and he has a new arm by the end of the game]].
** Though really it was more of a choice between [[spoiler: Snake's life and his limb]] at that point.
* Zul'jin from ''VideoGame/{{Warcraft}}'' is revealed in the Zul'Aman cinematic to have cut off his own arm to escape from High Elves who had captured him and had been torturing him (the torture is how he lost his eye). This is an odd case in that Trolls of the series can normally regenerate limbs including arms unless cursed or forsaken by their Loa Gods, but Zul'jin is still missing the parts years after the event, making it unclear as to how much a sacrifice he thought he was making.
* General Warfield from ''VideoGame/{{StarCraft II}}'' was hit in his arm by hydralisk spikes. He returns to base to have that arm cut off -- and replaced by an ArmCannon.
* ''VideoGame/TheDig'' has a memorable section where Brink's hand becomes stuck in the rock as it shifts while he tries to grab a life crystal in the rock, and the player has to figure out how to set him loose before gangrene or starvation sets in. Solution? [[spoiler:Use a jagged-toothed alien jawbone to ''saw his goddamn hand off''.]]
* ''HeavyRain'': "Are you prepared to suffer to save your son?" [[{{Fingore}} You have five minutes to cut off the last section of one of your fingers in front of the camera."]]
** You have ''options''. Some are far less pretty than others.
* The choice is made on behalf of one character in ''VisualNovel/shitoShoujo.'' In order to save [[spoiler:Kuchiki Toko]] the hospital opts for limb removal due to her poor condition. However, by this point, most of the limbs probably wouldn't have worked well anyway.
* ''VideoGame/{{Prototype}}'' has General Randall, head of BLACKWATCH forces, who's left arm is missing. Diving into the [[AllThereInTheManual Web of Intrigue]], you learn that [[spoiler: he was part of the initial operation in Hope, Idaho, and got infected with the Redlight virus. He managed to hack off the affected limb before it could spread to the rest of his body.]]
* In ''VideoGame/{{Mother 3}}'', when the party first meets Kumatora, her leg is caught in a trap, and she decided to try and cut her leg off to get out of the trap. It's a good thing that your party came along when it did.
* Comes up twice in ''VideoGame/TheWalkingDead'' video game:
** At the very start of Episode 2, the protagonist Lee finds a man caught in a bear-trap, with zombies being drawn to his cries for help. You can choose to either leave the man to his fate, or cut his leg off to free him. [[spoiler:Subverted, [[RealityEnsues as he ends up dying from blood loss]]]].
** The player is presented with this choice again early on in Episode 5. [[spoiler:This time, the choice is whether or not to cut off Lee's bitten arm. Again, subverted in that Lee eventually dies no matter what choice is made: he either falls victim to the virus, or dies from shock and blood loss.]]
** In Episode 3 of Season 2, the group meets Reggie, a man who was in this situation before and had his arm cut off quickly enough so that the infection didn't spread. [[spoiler:At the end of the episode, Clementine is given the option of doing this to Sarita when she's being attacked by a walker, though regardless of your decisions she's immediately sicced by another of walkers in the next episode.]]
* A drunken encounter on ''VideoGame/KingdomOfLoathing'''s analogue of Saint Patricks Day can end in a 'coyote moment':

* ''Webcomic/LookingForGroup''. Warlock Richard is bound by a set of enchanted shackles which are drawing their power from him. The group's healer severs his arms in order to deprive the shackles of their power source, rendering them inert. Subverted in that Richard doesn't appear to be able to feel pain, and that Benny's powers make reattaching his arms a simple matter.
* In ''Webcomic/SchlockMercenary'' a murder case where an arms dealer's severed hand seemed to have died several minutes after the rest of him turned out to be an instance of this.

[[folder:Western Animation]]
* In ''WesternAnimation/JusticeLeague'', Aquaman had to cut off his hand to free himself and save his son from a deathtrap. Do note that he could just break the chains, but that would take more time and [[PapaWolf could endanger his son]].
* Being one of the most horrific thing that could happen to someone, ''WebAnimation/HappyTreeFriends'' [[CrossesTheLineTwice of course makes a joke out of it]]. One of Lumpy's legs is trapped by a falling tree and he spends the next three days hacking his leg off. With a spoon. After finally finishing he finds [[ShaggyDogStory he cut off the wrong leg]]. And then the spoon breaks, so he has to use a paperclip.
* This "coyote moment" comparison was [[RunningGag used for great fun]] in a chapter of ''WesternAnimation/TheFairlyOddParents'' where Timmy, accosted by his neurotic, overdemanding crush, began to nervously chew the arm she is holding, and the girl [[StrangeMindsThinkAlike immediately quotes the coyote metaphor]] and [[LampshadeHanging correctly guesses his intentions]]. Albeit no limb was chopped, the intention was there.
* ''WesternAnimation/SouthPark'': Although it happens offscreen, at the start of one episode, Cartman is being reprimanded for handcuffing a kid to the school flagpole then telling him he slipped poison into his milk and he would have to saw through his own ankle to get to the antidote. [[DisproportionateRetribution Just because the kid called him fat]].
* On (presumably) the last episode of ''WesternAnimation/ElTigre'', Manny tried using his extendable arm to catch [[spoiler:Dijango of the Dead]], only for him to set the chain on fire, leaving Manny no other option than to cut it off. Good thing he has a spare at home...
* Subverted on ''WesternAnimation/TheSimpsons'' when Homer has his arms trapped inside two vending machines. The fire department are about to cut one of his hands off, when it's revealed that [[TooDumbToLive he just won't let go of the can]].
** A ''TreehouseOfHorror'' episode parodies the Aron Ralston incident (see Real Life section), when Homer Homer gets his arm trapped under some boulders while hiding in the Springfield badlands to eat some Halloween candy, and has to chew off his own arm. After many painfilled hours, [[EpicFail he notices he chewed off THE WRONG ARM]]and has to do it all over again. [[ShaggyDogStory Then he discovers that Bart and Lisa took the candy, since it was theirs in the first place, and replaced it with vegetables]].
* Subverted on ''WesternAnimation/{{Futurama}}'', when a hopelessly Slurm-addicted Fry makes a ''Soft Drink'' or Limb Decision, and attempts to chew off his own arms so he can fit through a grating in pursuit of the Royal Slurm.
* Played for laughs in ''WesternAnimation/SpongebobSquarepants'' episode "Idiot Box", when [=SpongeBob=] and Patrick decided to play Mountain Climbing Adventure! Their constant yelling and laughing triggered an avalanche.

[[folder:Real Life]]
* Coyotes are supposed to chew their own leg off if they get caught in a trap. This leads to the expression "coyote moment". Probably irrelevant, it's about dating: "When you wake up with them sleeping on your arm, and would rather chew it off than wake them."
** In TylerPerry's ''Diary of a Mad Black Woman,'' Medea is under house arrest and is trying in vain to get the electronic ankle bracelet off, when her brother tells her about coyotes and says, "Want some hotsauce?"
* Many lizards have tails that cleanly break away from their bodies when a predator grabs them by it. Often the tail continues to twitch after such self-amputation, as a further distraction for the predator. Interestingly enough, this can sometimes be a win-win for both the lizard and the predator; Not only does the lizard escape with its life, but the predator will occasionally settle for eating the lizard's tail after it breaks off.
** Oddly, gerbil tails work the same way--the "tearing off to let them get away" part, that is. Not the twitching part. And it's the skin around the terrified gerbil's tail, not the internal skeletal structure that falls off a couple days later.
** Sloughing off the skin of one's tail when it's grabbed or caught on something is a common defense for many long-tailed rodents, not just gerbils. If you see a squirrel with a less-fluffy tail than usual, that's probably what happened to it.
** This (along with terrible pain) is why pet rats should never be lifted by their tails.
* TruthInTelevision: [[http://en.wikipedia.org/wiki/Aron_Ralston Aron Ralston]], number six on the ''Cracked'' article "[[http://www.cracked.com/article_16497_7-people-who-cheated-death-then-kicked-it-in-balls.html 7 People Who Cheated Death (Then Kicked It In The Balls)]]". While mountain climbing, one of his arms got trapped under a fallen boulder... so he cut it off. With a ''penknife''. ''A '''dull''' penknife''. It was sharp when he started out, but he first tried to use it as a lever to get the rock off, dulling the blade. He had to snap the bone completely in two before he could start cutting.
** Even worse, Aron decided to wait a few days, hopeful that someone would come and rescue him. No one ever came. So he had to cut off his own arm, with a dull penknife, ''while dying of thirst''. And ''then'' he had to survive climbing back down the mountain!
*** WordOfGod is he waited the exact right amount of time. Any longer, and he would have been too weak to reach help before dying of blood loss. Any earlier, and the search would not have been developed enough to get him medivaced in time once he did find help to save him from bleeding out.
** This incident has been made into a 2010 movie: ''OneHundredAndTwentySevenHours'', starring JamesFranco.
* A similar thing happened to a man named Jonathan Metz, whose arm became trapped behind his boiler when he tried to clean behind it. He realized that not only was he going to die if he didn't cut his arm off, so was his pet beagle Portia, who was wandering around upstairs, hungry and confused as to why he he had disappeared. It was the realization that her barking fits were becoming shorter and less frequent, coinciding with his own weakening state, that made him resort to such drastic measure. Much like the Ralston example, his timing was perfect--the arm hand become gangrened enough that it was relatively painless, and police and EMS crews were converging on his house, alerted by friends who were alarmed by his disappearnce.
* RealLife: During the Manhattan Project to create the first atomic bomb, it was stated that if you accidentally poked a limb with a plutonium-contaminated tool, the only recourse was swift amputation.
** Used in a fictional book when someone does so and they grab a nearby rotary saw and cut off his arm.
** ''Film/DoctorNo'' used this premise to account for No's robotic hands.
* There was one instance of a man who caught a ball of cobalt-60 and had his hand amputated. This would not have been necessary as Plutonium nuclides are actually pretty benign, as far as radiation goes. However, this was not known at the time, like most of the properties of plutonium (which was only just available in macroscopic quantities, and only because of the bomb effort itself). The two incidents with the Demon Core only served to further elevate fears about the lethality of the stuff.
* The Civil War. In fact, the civil war hospital where a guy gets a shot of whiskey and a block of wood to bite on while they saw off his legs should be a trope of its own.
** Any war before WWII, when antibiotic drugs were invented, not only the American Civil War. Before antibiotics, gangrene was almost unpreventable when wounds got infected.
*** Considering the effect that .75 caliber Civil War era bullets would have on an arm or a leg, you could get shot today in the most advanced hospital available and still lose the affected limb.
* Horrifically subverted in Sierra Leone's own civil war, when rebel war criminals would ask their victims, "Short sleeves or long?", then amputate their hands at either the elbow (short) or the wrist (long). Either way, victims' survival depended on whether the bleeding could be stopped, not on what they chose.
** Some rebels practiced a straight version of the trope, merely asking "Hand or head".
* Crossed with DarkComedy in the warnings on some large woodchippers -- something to the effect of "Do not stick arms or legs into machine -- machine can pull you in faster than you can let go of limb."
* Occasionally invoked by rescue workers to retrieve victims of auto pileups or collapsed buildings.
** Emergency medical responders have the basic rule "Life over limb." While this doesn't usually involve amputation, it does mean that given the choice between risk of death by not moving them because they have an unsecured spinal injury as opposed to moving them out of the immediate life-threatening situation and risking spinal damage, well, they might end up in a wheelchair but they'll be alive to do so.
* [[http://articles.nydailynews.com/2001-07-13/news/18359595_1_baler-arm-surgery-auto-mechanic This news story]] about a man who was forced to cut off his own arm when it was caught in a hay baler in order to stop himself being dragged in.
* Frostbite occurs when someone's physiology makes a LifeOrLimbDecision of its own, withdrawing blood flow from the extremities in a desperate attempt to keep the body's core, and the vital organs inside, from freezing. Better to sacrifice digits, earlobes, nose or even whole hands and feet than to lose the brain or viscera.
-->'''[[{{Literature/Twilight}} Bella Swan]]''': "-n-n-nobody really n-n-n-n-needs all ten t-t-t-toes."
* "If your right hand causes you to sin, cut it off and throw it away," etc. (see the Religion section above). Well, the Church Father Origen took this advice quite literally. However, [[GroinAttack it's wasn't his hand]] [[ShareTheMalePain that was doing the sinning.]]
* Octopuses can regrow arms, so they've been known to leave an arm to get eaten and swim away, or even to ''eat'' their own arms in times of extreme starvation.
* For years, it was believed that this would be the case if one had to apply a tourniquet for more than a few minutes. Tourniquets will stop bleeding by cutting off circulation to the limb, and it was long assumed that this would result in loss of said limb (or at least part of it) if left in place long enough. For this reason, tourniquets were only recommended in cases where a person's life was in danger from bleeding out of a wound (a literal life-or-limb situation). However, recent research conducted by the US military has proven that a tourniquet can be safely left in place for up to 45 minutes without requiring amputation. Tourniquets are now recommended in cases where direct pressure has not controlled the bleeding, and the patient will reach the hospital within 45 minutes.
