A grappling hol (commonly referred to simply as a hold; in Japanese referred to as katame-waza, 固め技, "grappling technique") is a grappling, wrestling, judo or other martial arts term for a specific grip that is applied to an opponent. Holds are principally used to control the opponent, and to advance in points or positioning. Holds may be categorized by their function such as clinching, pinning, pain compliance or submission, while others can be classified by their anatomical effect: chokehold, joint-lock or compression lock.
