The thumbscrew is a torture instrument which was first used in early modern Europe. It is a simple vice, sometimes with protruding studs on the interior surfaces. The crushing bars were sometimes lined with sharp metal points to puncture the nails.
Eventually, the thumbscrew would break one or both bones in the thumbs, and the absolute agony made the thumbscrew one of the most effective torture devices in history. The apparatus inflicted unbelievable pain without killing someone.
