Country Dictionary

slang for the government issue p 38 can opener. The P-38 can opener is a small device issued in the canned field rations of the United States Armed Forces from World War II to the 1980s. Originally designed for and distributed in the K-ration, it was later included in the C-ration.

It was developed in 1942.

Nicknamed the "John Wayne" because he was shown in a training film opening a can of K-Rations, the can opener is keychain sized and consists of a short metal blade that serves as a handle (and also a screwdriver to the resourceful), with a small, hinged metal tooth that folds out to pierce the can lid. A notch just under the hinge point keeps the opener hooked around the rim of the can as the device is "walked" around to cut the lid out. A larger version called the P-51 is somewhat easier to operate.
