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. These can end up as Cumbersome Claws if the character isn't careful about handling things.
- 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. They're part of a group of weapons called "Dramon Killers" and like their name applies, they can kill Dragon-type Digimon. 2 of the Dark Masters were Dramon-type and when pitted against War Greymon, well you can see what happens next.
- 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 a Historical Domain Crossover scenario. Lucrezia Borgia serves as an agent of the Hell Lord Satannish. She is granted Absurdly Sharp Claws coated with poison.

- 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.
- Jaune Arc, Lord of Hunger:
- The terentatek that attacks Jaune in "Fear" has claws which can rip apart an armored human as if they were made of tissue paper. A single slash is all it took to destroy Jaune's Aura, tear through his armored chestplate, and gut him like a fish.
- The Wyvern Grimm that attacks Vale during the Fall of Beacon is able to tear through the armored plating of a military airship and damage the ship's engines using its talons alone.

- As per canon, Wolverine, Daken, and Sabertooth have their (duh) Wolverine Claws in Child of the Storm.
- In Zero Context: Taking Out the Trash, the human-Delcatty hybrid Callista possesses these as a superpower. They're noted as being able to slice through titanium alloys from a standing start, with their potency increasing alongside her speed. According to her, when she's at her fastest, her claws become so sharp that the fabric of reality's existence is endangered, so she makes it a point to avoid going all-out for this reason.
- The Lion King II: Simba's Pride: At one point during "My Lullaby," Zira rakes her claws against a rock wall, leaving deep gouge marks.
- The Hawk in Rango sees the titular hero hide in a bathroom stall, so she give it a single swipe from her talons, then multiple perfectly parallel pieces of the stall slide off one by one.
- Puss-in-Boots from the Shrek series is often seen cutting glass with one claw, very quickly. Puss generally picks his fights using his sword. In Shrek the Third, Donkey attempted to duplicate the trick after being body-swapped with Puss, but due to lack of skill, it didn't quite work.
- 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 John Carpenter's Vampires, the Big Bad vampire cuts a human cleanly in two with just his claws.
- Split Second (1992), 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.
- When she's in her Cat Girl form, Danielle from Mind Games has claws on both her fingers and toes that count as System weapons, which means they're more dangerous than bullets to most System-empowered beings.
- 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.
- Interview with the Vampire (2022): Vampires have razor-sharp fingernails that serve as claws, and they use them to mutilate their human prey.

- 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—*BLAM*) 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.
- Vampire: The Masquerade has the Protean Discipline and its power of Feral Claws, which allow a vampire to grow sharp talons that do aggravated damage. Other things that do aggravated damage to vampires include fire and sunlight, so that's about the level that these things are on.
- 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.

- 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.
The dwarf militia commander scratches the goblin axeman in the right lower arm with his left hand and the part is ripped into loose shreds!
