Razor Fist is the name of three different supervillains appearing in American comic books published by Marvel Comics. The original Razor Fist was killed off in the comic books many years ago. The next two characters to take the title were brothers. The current Razor Fist is the only surviving brother.

Florian Munteanu portrays Razor Fist in the Marvel Cinematic Universe film Shang-Chi and the Legend of the Ten Rings.

The first Razor-Fist is an assassin, bodyguard, and enforcer employed by Carlton Velcro, who replaced his hands with steel blades. He battles Shang-Chi before being killed by Velcro's guards.

Doctor Doom later creates two robot duplicates of Razor Fist, which he pits against Shang-Chi.

The Scott brothers are servants of Carlton Velcro who each lost a hand in a car accident. After Velcro accidentally kills William, Douglas is defeated and captured by Shang-Chi and Pavane. Sometime after William is killed, Douglas loses his other hand and replaces both his missing hands with blades.

In New Avengers, the Hood recruits Razor Fist, among other villains, into his gang to take advantage of the split in the superhero community caused by the Superhuman Registration Act.

Each Razor Fist has no known superhuman powers. However, each Razor Fist's physical strength, speed, stamina, agility, and endurance are honed to the peak of human conditioning. The first Razor Fist's hands were both surgically replaced with steel blades which he used as weapons, while the former two Razor Fists initially had only one hand replaced with a steel blade. The last remaining Razor Fist eventually had his other hand replaced by a similar blade as well.

Each Razor Fist is highly skilled in multiple forms of combat, with extensive training in hand-to-hand combat and martial arts.
