The mutilation shears were used not as a primary torture implement, but rather as something of a ‘clean-up’ device. After a prisoner’s fingers or toes had been thoroughly crushed by other means, the mutilation shears were employed to cut the broken extremity from the body.

The side screw was used to increase the force between the shears, as it is surprisingly difficult to cut through some tendons and even more so through bone.
