P-38 can opener

The P-38 is a foldable carbon steel can opener that was issued with canned United States military rations from its introduction in 1942 to the end of canned ration issuance in the 1980s. Originally distributed in the K-ration, it was later included in the C-ration. A larger later variant is known as the P-51.
