The Head Crusher was also a widely used form of torture. the head crusher was an instrument that contained a bottom bar, a cap, a screw-type compressor and side supporting bars. When someone was punished by the head crusher what happened was this;
Their chin was placed on the "bottom" bar, with type cap on top of their crown-their head. Then the torturer started twisting the compressor device. This started to slowly crush the head. There were various stages in the head crusher, a couple of these stages were:
- The teeth were shattered into the jawbone.
- The eyes popped out of their sockets.
