I am coming up with a kind of weapon a supervillain builds himself with fairly modern materials/tech. He uses it as a weapon, but also as a device for lacerating and torturing his victims.
I’m imagining a kind of steel glove with long claws (maybe 3-4 inches) on the fingertips. Each finger joint has a little gear, sort of like a park gear on an automatic transmission, that can either rotate freely or be locked in place at fixed points along the rotation of the joint. Each joint, including the base of each finger and the wrist, would have this mechanism, restricting its freedom of movement somewhat but allowing for the fingers not to break and dislocate when “slashing” with the claws by locking them up. I was thinking the glove may even extend past the elbow, having another locking gear on the elbow so it doesn’t break or buckle. Ideally, whenever any joint is unlocked and moved about, it would make an ominous “clicking” noise like a free-spinning bicycle gear, so extra points if that can happen.
Assuming the villain has very strong fingers, would this be an effective weapon/torture device with a bit of hand-waving, or is it too complicated/too much risk of pinching fingers? How could the design be improved/made more brutal?
