US P-38 Military Can Opener is a simple but highly effective tool for opening cans. Designed during WWII, it is still used today by the military and in relief operations throughout the world. The P-38 Military Can Opener is roughly 2/3 the size of the P-51 can opener and small enough to fit on your key chain. The P-38 Can Opener also does triple duty as a small pry tool and flat head screw driver as well.
