How did thumb screws work?
A thumbscrew works thanks to three upright metal bars. The middle bar contained threads for the screw. In between the metal bars, the victim placed their thumbs. The people interrogating the person would slowly turn the screw, which pushed a wooden or metal bar onto the thumbs and squeezed them.
What is a knurled screw?
Thumbscrew can mean: Thumbscrew (fastener), a type of screw with a tall head and ridged or knurled sides, or a flat vertical head, intended to be tightened and loosened by hand.
