P-38 can opener

Vietnam-era P-38

P-51 and P-38 openers

The P-38 'Lightning' is also a WWII-era plane. The Walther P 38 is a WWII-era pistol.

The P-38 can opener is a small device found in a C-ration, the canned field rations issued in the United States Armed Forces from World War II to the 1980s.

Nicknamed the "John Wayne" for its rugged reliability, 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.

Official military designations for the P-38 include 'US ARMY POCKET CAN OPENER' and 'OPENER, CAN, HAND, FOLDING, TYPE I'. As with some other military terms (e.g. Origin of the term 'jeep'), the reasons for the 'P-38' designation are not clear. One claim is that, used properly, it requires exactly 38 punches of the blade to open a C-ration can. Alternatively, the name could allude to the fast performance of the P-38 'Lightning' fighter plane.

P-38s are no longer used for individual rations by the United States Armed Forces as canned C-rations were replaced by uncanned MREs in the 1980s. They are, however, included with US military "Tray Rations" (canned bulk meals), and are also still seen in disaster recovery efforts and have been handed out alongside canned food by rescue organizations both in America and abroad in Afghanistan. The original US contract P-38 can openers were manufactured by Mallin Hardware (now defunct) of Shelby, Ohio and are stamped "US Mallin Shelby O.".

A similar device that incorporates a small spoon at one end and a Can opener at the other is currently employed by the Australian Army and New Zealand Army in its ration kits. It is known by the acronym "FRED" (Field Ration Eating Device). It is also known widely in its derogative term, the "Fucking Ridiculous Eating Device".

The advantages of a P-38 include:

• cheaper to manufacture than a standard can opener
• smaller and lighter to carry
• faster than a normal can opener if the user has sufficient experience

The device can be easily attached to a key ring or dog tag chain using the small punched hole.
