This metal device featured a plate that sat below the victim's jaw, which was connected by a frame to the head cap. As the torturer slowly twisted the handle, the gap between the head cap and plate decreased in width, causing crushing of the skull and facial bones, including teeth and jaws, and ultimately inducing death; even if the torturer stopped before death, permanent damage to the facial muscles and structure would occur. The victim's head would slowly be crushed, killing the victim, but not before the victim's jaw had been crushed, and their eyes had popped from their sockets.[2]

There were many variations of the head crusher during the Middle Ages, some of which even had a container in the front to catch the popped eyes of the victim.[1]
