10 cruel torture devices designed to cause huge pain (With Pictures)

7. Knee Splitter

Knee Splitters were employed in the 12th century, during the Inquisition. The contraption had two wooded blocks with spikes. The number of spikes ranged from 3 to 20, and depended on the gravity of the crime committed by the person being punished. These spikes are driven into the flesh of the victim, and once the spikes are embedded into the victim’s leg, the blocks are drawn closer to each other using two large screws, to slowly pulverize the knee, just as the device’s name suggests.
