Zael: Chin up, lad! Got Terminator Armor, after all!
Gideon: I seem to remember Genestealers having Rending Claws, Zael. This armor's about as protective as wrapping your dick with a napkin to fuck a chainsword...
In Real Life, animals use their claws for various purposes (hunting, climbing, grooming, digging, defense, etc.). However, over time, these claws grow dull and must be sharpened to maintain their usefulness.
Not so in the world of fiction. In many fictional cases, animal claws remain insanely sharp even after constant use. Moreover, these claws are so sharp that they are effectively natural swords able to slice through things that few (if any) real life animals could ever scratch. Werewolves, dragons, Mons, and other superpowered animal characters can be expected to use this trope.
Subtrope of Absurdly Sharp Blade. May overlap with Blade Below the Shoulder (the permanently-attached variant) and its subtrope Wolverine Claws, depending on whether the claws replace the entire hand (the former) or not (the latter). May have Audible Sharpness.
- Fullmetal Alchemist:
- Lust is known as the Ultimate Spear, and hasn't been shown to be unable to cut anything. Strictly speaking Lust herself is not natural, making for kind of a gray area in the trope.
- Greed, also a homunculus and in the same gray area, has claws on his Ultimate Shield that are able to cut into stone. No in-universe evidence was ever given as to whether Lust's Ultimate Spear could cut Greed's Ultimate Shield.
- Ultimate Muscle: Thunder's left shoulder possesses a large lion's claw when it is used for his Lion's Authority Signature Move.
- Digimon has a few:
- Snimon's blades are no less dangerous than his Pokemon counterpart Scyther. It comes with a Razor Wind attack.
- Beelzemon's Darkness Claw attack has given opponents the Delayed Reaction death Diagonal Cut treatment.
- War Greymon's gauntlets have given the Wolverine treatment to otherwise untouchable foes. They're Made of Indestructium and absurdly sharp.
- See anything under Digimon's BFS listing, though it could be that the physical strength of the wielder, typically a Mega Digimon, is a factor too.
- Rosario + Vampire:
- Yu-Gi-Oh!: Several monsters attack with sharp finger nails.
- Yu-Gi-Oh! GX: Most notable example is Raviel, Lord of Phantasms. His attack name is Shimmering Scraper. Coming from a giant monster with sharp claws, it definitively hurts.
- Apparently, many youkai and hanyou have this in InuYasha. Koga often uses his claws in combat, and Inuyasha this does also.
- Claymore has Rigardo. He visually resembles a werelion, but he is an Awakened Being, and fights with his claws and Super Speed. On his first appearance, he kills four out of the five highest-ranking warriors on the battlefield faster than they can react.
- In Ginga: Nagareboshi Gin, Sniper kills a dog named Lloyd by clawing his head. The bears as well are often shown tearing open either a person or dog with a single strike of their claws.
- Happens as a gag in Cattivik when the titular character is cut to ribbons by a lion.
- Wolverine has shown he still has tremendous cutting power even when he just has his natural claws, which are noted to be made of dense bone rather than keratin. By extension, this also applies to Daken and X-23, although the former's natural claws are actually of some kind of metallic composition, and the latter had hers coated with adamantium before they ever saw any real use. Sabertooth is another example, with smaller, more cat-like retractable claws in his fingers that have been known to cut steel.
- A storyline in Avengers West Coast #98-100 (September-November, 1993), features an Archived Army scenario. Lucrezia Borgia serves as an agent of the Hell Lord Satannish. She is granted Absurdly Sharp Claws coated with poison.
- The Venom and Carnage symbiotes can shape shift to form razor-sharp claws and arm-blades.
- Peanuts: The cat who lives next door to Charlie Brown and Snoopy is able to rip large portions of Snoopy's doghouse off in a single swipe, though it's unclear whether this demonstrates sharpness or sheer brute strength. Either way, you wouldn't want to meet that feline in a dark alley.
- In Fearless, one of the opponents Huo Yuanjia fights uses a form named "Tiger Claw" that involves him scratching h is opponent with his bare nails. Apparently, he can slowly rip your shirt if you let him get close enough.
- In Van Helsing, werewolf Gabriel leaves claw-marks on a stone statue during his brawl with Dracula.
- In John Carpenter's Vampires, the Big Bad vampire cuts a human cleanly in two with just his claws.
- Split Second, the 1992 Rutger Hauer movie, is a great example for this trope. The creature uses its huge claw to shred through the roof of a subway train like a hot knife through butter. It has to be seen to be believed.
- The monsters from Feast are described as having 'claws like Ginsu Knives'. and they can easily tear apart humans.
- The small stone gargoyle creatures in the horror film Curse of the Talisman have sharp claws strong enough to tear into cars.
- The claws of the monsters in A Quiet Place can cut through pretty much anything the plot demands, including metal plates, until the Rule of Drama dictates they suddenly can't.
- Andalite tail-blades in the Animorphs-verse are demonstrably sharp enough to cut metal and lop off limbs.
- In Dragonback, K'da claws are sharp enough to cut through metal. And not just slash through it either; at one point Draycos uses this ability to carve a precise hole in a shuttle's hull as sabotage.
- The One Who Eats Monsters: The protagonist, Ryn, has fingernails so sharp that they can, quote, "Kill anything that can die, and a few things that cannot".
- Sirens in Into The Drowning Deep, possess claws sharp enough to dig into metal walls, allowing them to climb sheer surfaces.
- Doctor Who: In "Gridlock", the Macra can be found at the bottom of the motorway in New New York (on New Earth). In the "fast lane" you can reach speeds of up to thirty miles per hour! (Usually taking six years to get to Brooklyn from Queens!) However, this comes with a risk: the potential of being sliced and mauled by the Macra. What's even scarier is that you only really get to see these claws above the fumes.
- Star Trek: Voyager: The main mode of attack of Species 8472 (the Undine to Star Trek Online players). One swipe can decapitate a helmeted Hirogen.
- In the Supernatural episode "Heart" (S02, Ep 17), we find that werewolves have thick gray claws that leave scratch marks in the side of a concrete building.
- As mentioned in the page quote, in Warhammer 40,000, any tyranid strain from the Genestealers and up can rip open Powered Armor, and the larger monsters open tanks like cans.
This forms the basis of a minor Running Gag/Noodle Incident in the Ciaphas Cain (HERO OF—*las shot*) series, where the first time in any book the 'nids are mentioned, Cain recalls a time he saw genestealers tear apart Space Marine Terminators as if their armor wasn't there. We finally get to see it in the seventh book.
- In Pokémon, the move Cut allows the player's Pokemon to cut down small trees with a single slicing movement. Flavor Text for various Pokémon species describes how their claw/pincer/etc. weapons are sharp enough to inflict significant property damage. Also repeatedly demonstrated in the anime, with Scyther* in particular repeatedly seen chopping down trees in a single swipe.
- Iori Yagami from The King of Fighters practices his clan's ancient martial art, which entails pyrokinetic blasts and slashing with his fingertips like razor-sharp claws.
- In Evolva, the Genohunters are able to get claws able to slice rock walls to pass through them.
- Fallout features the aptly named 'Deathclaws', genetically engineered killing machines with claws the size of knifes. In each game they are one of the toughest commonly occurring enemies, and their claws can even be Macgyvered into one of the more deadly unarmed weapons in the game.
- [PROTOTYPE] has this as one of the first upgrades, which is a Disc-One Nuke for crowd clearing.
- In StarCraft, fluff describes the zerg ultralisk, their equivalent to a tank (think an elephant with scythes instead of tusks), as having blades with a monomolecular edge.
- Arx Fatalis features the Black Beast, the monster from the bowels of the earth possessing foot-long, One-Hit Kill claws. Seconds before you meet it, you have to crawl through the tunnel that is apparrently burrowed in solid rock, with Wolverine-like claw marks all over the floor and walls.
- Dwarf Fortress has an interesting case, in that anything that has nails can cause grievous damage through scratching. While this includes obvious and reasonable creatures like tigers and badgers, this also includes things like dogs, goblins and your very own dwarves. While they can't remove limbs, dwarven nails have been known to cut through tendons, shred right through muscle and nerve tissue, and even eviscerate people. There is a popular technique among veteran adventurers that involves doing a Barehanded Blade Block with one hand and scratching their wrist tendons off with the other to steal their weapon.
- In Gosu, Wang Eungi cleanly cleaves through solid boulders with nothing but his nails (and powerful outer ki skills).
- A Wile E. Coyote short in The Looney Tunes Show has Wile E. being sliced to ribbons by the Roadrunner's talons in a ninja-style battle.
- The titular species in Gargoyles have claws that are strong and sharp enough leave deep scratches in solid concrete and even solid steel. This is actually how they climb buildings and cliffs.
- My Little Pony: Friendship Is Magic, "Stare Master": Rarity's cat Opal cuts off a lock of Sweetie Belle's mane with a swipe of her claws.
