P-38 Can Opener

P-38 Can Opener

During the WWII, Korean and Vietnam Wars when GI's were ready to devour their delicious meals of K or C-Rations they used their trusty P-38s to open the cans. It wasn't the famous WWII fighter plane or a German pistol, it was an amazingly simple little piece of 1-1/2 inch stamped metal that was developed in just 30 days during the Summer of 1942 by the Subsistence Research Laboratory in Chicago.

It's official designation is 'US ARMY POCKET CAN OPENER' or 'OPENER, CAN, HAND, FOLDING, TYPE I', but it is more commonly known aas the P-38, 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" by those in the Navy and Marines because he was shown opening a can of C-Rations using a P-38 in a WWII training film. From then on Sailors and Marines referred to them as a "John Wayne".

Originally P-38s came wrapped in brown Kraft paper packets with a diagram and directions how to use printed on it. This is the information taken directly from the wrapper:

CAN OPENER DIRECTIONS
Open blade. Place opener as shown in diagram. Twist down to puncture slot in can top inside rim. Cut top by advancing opener with rocking mo-tion. Take small bites.

STERILIZE BEFORE RE-USE
Tie string through hole in opener to wash and ster-ilize with mess-gear if possible. When boiling water is unavailable, clean opener as thorough-ly as possible and hold cutting blade over a match flame a few sec-onds immediately before use.

About a dozen P-38s came packed in a case of C-Rations. Because everyone was hoarding them only 3 were included in a case. These handy gadgets have adorned the dog tag chains and key rings of WWII, Korean and Vietnam war vets ever since opening their first can of C-rats with one. I wear one on my dog tag chain. The word SHELBY is almost worn off. I also have one on my car key chain and mototcyle key chain.

GIs held C-Ration can opening races using P-38s which were usually won by who could open a C-rat can in less time than it takes to read this sentence.
