What does chiv mean?
"Chiv" is an informal British term for a knife or other sharp-edged weapon used as a stabbing implement, particularly one that is improvised rather than manufactured — a ground-down piece of metal, a sharpened file, or similar makeshift blade. The word belongs firmly to slang, and historically to the vocabulary of prisons, street gangs, and the criminal underworld, where naming weapons obliquely was both practical and customary. As a verb, to "chiv" someone is to stab them, though this use is now rare outside historical fiction and accounts of old penal slang. The better-known American equivalent is "shiv," which appears to be a variant of the same word and has largely taken over the meaning in contemporary usage. Today "chiv" survives mainly in dictionaries of slang, in writing about Victorian crime, and among readers of older British fiction, where it lends period flavor to depictions of the rougher side of life.
A knife or improvised sharp weapon used for stabbing, especially in criminal or prison contexts.

Regular plural; used when referring to multiple such weapons, most often in accounts of searches, confiscations, or underworld settings.

Before 'shiv' ruled American prison yards, its older British cousin 'chiv' was already doing the same dirty work in Victorian underworld cant.

Etymology of chiv
The origin of "chiv" is uncertain, but it emerged as British underworld and prison slang, recorded from at least the seventeenth century in canting dictionaries and later criminal literature. It may derive from the Romani word for knife or blade, which would place it among the many words that entered English criminal argot via contact with Romani speakers, though this connection is debated by etymologists. The American prison term "shiv" appears to be a phonetic variant of the same word, showing how the item and its name traveled across the Atlantic.
How chiv is actually used
Strongly informal and associated with criminal, prison, or historical underworld registers. In modern American English, "shiv" has largely displaced it; "chiv" now reads as dated, dialectal, or deliberately archaic.
