shiv

A shiv is a slang term for a knife, especially a switchblade. It is most often used to refer to improvised blades made in prison and the act of stabbing (shivving) fellow inmates or guards with them.

Shiv originates in British thieves’ slang term for a “knife,” chive or chiv, dating back to the 17th century. It is thought that chive and chiv are rooted in a Romany word for “blade.”

Shiv is an American English version of chive showing up as early as 1897. In his memoir The Road, Jack London chronicles his days as a hobo. He documents a lot of slang he encounters while hopping trains, including shiv for”knife.”

Shiv (shivving, shivved) has been used as a verb since at least the 1930s. In the story “Dream Street Rose” by Damon Runyon, for instance, a character is shivved (“stabbed”) by another. Shiv spread as a slang term in prisons, especially for knives improvised out of material at hand.

Shiv is most often used to refer specifically to homemade knives in prison. A similar term to shiv is shank.
