U.S. G.I. P38 Can Opener
Developed in 1942 and issued from WWII to the 1980s. The P-38 is the name which it supposedly acquired from the 38 Punctures required to open a C-Ration can. It is also known by many as a "John Wayne" especially to those in the Navy and Marines because in a WWII training film he was opening a can of K-Rations using a P-38.
Being so small and lightweight, the P-38 is ideal for your backpack or bug out bag.
