From the 12-DVD series, Snap, No Tap! comes this demonstration of the catch wrestling top wrist lock "hook," as well as a brief description of the differences between concession holds / submission holds and the kind of maneuvers American catch refers to as "hooks." In short, a hook is a tighter and more severe version of a concession hold, and it designed to break or maim without giving an "opponent" recourse to concession.
