A shiv (from the Romani word chiv) is a slang term for a sharp or pointed implement used as an improvised knife-like weapon. The shiv is the favored weapon of inmates in prisons across the world. It is infamous for its versatility - a shiv can be anything from a glass shard with cloth wrapped around one end to form a handle, to a razorblade stuck in the end of a toothbrush, to a sharpened spoon. Some inmates have even sharpened the ends of pork chop bones to make them into weapons
