In professional wrestling, a cutter is a three-quarter facelock bulldog maneuver. This move sees an attacking wrestler first apply a three-quarter facelock (reaching back and grabbing the head of an opponent, thus pulling the opponent's jaw above the wrestler's shoulder) before falling backwards (sometimes after running forwards first) to force the opponent face-first to the mat below.
The cutter was originally used by Johnny Ace, who called it the Ace Crusher, and by Diamond Dallas Page, who called it the Diamond Cutter, from where the term "cutter" is now derived. The cutter also formed the base for the later development of another professional wrestling move known as the stunner. This variant sees an attacking wrestler apply the facelock but, instead of falling to their back, this wrestler drops to a seated position, dropping an opponent's jaw across the shoulder of the wrestler.
A cutter is sometimes described as an inverted neckbreaker, though it is not one.
