Gomco Clamp 

A fucking scary device used to circumcise a penis. Kinda looks like Satan's toenail clippers, or maybe some German masochist's stapler. Basically a vise specially shaped to fit a penis. Can exert up to 20,000 pounds of crushing force. Google it if you're curious -- and brave.

Just the thought of a Gomco Clamp makes my dick hurt.
