The hand forged punishment clamp its my take on the old fashioned thumb screws. I have modified the design for fetish and bondage use so then its more playful but still has a torturous feel. The clamp is made to look medieval with a rustic finish to give a realistic experience. The crusher bar is made from an old rasp to make sure it has a bite. The opening is big enough for the executioner to choose what goes in and it can be adjusted using the screw to apply more pressure.
