Cuban Crafters has sold metal versions of these for years called Perfect Cutters. They actually have a small round hole in the middle of the back stop so you can cut torpedos and such as well. I bought one a few years ago for a really cheap price at the time and used it on and off for several years when it crossed my path. It's nice to use when you um maybe have had one or ten too many to drink and keeps the cap from falling to the floor in a friends car as well.
