The John Wayne: True facts about the P-38 Can Opener

Posted by Chip C. on 28th Mar 2024

G.I. Type 12-pack P-38 Can Openers Made In USA

12 Pieces in a Poly-bag, With Mil-j-0837 Engraving , 1 1/2 Inches X 5/8 Inches , Tip Extends 1/2 Inch.

The P-38 was originally developed in 1942 for the U.S. Military field rations; made out of stamped steel and were issued with K-rations to the troops. K-rations were later replaced by C-rations and the P-38 remained a soldier's companion. In the 1980's, the author first came in contact with the C-rations which were replaced by Meals-Ready-to-Eat (MRE) during the same decade and the need for a can opener was no longer needed. Also known as the “John Wayne” style can opener, although we don't know why it got this moniker, unless maybe he used one in "Sands of Iwo Jima" or some other WWII production. Attached to a key chain or dog tag chain, this manual can opener is a small but useful tool that has been used by generations of military personnel and is a great addition to anyone's survival kit! The key chain/dog tag chain hole allows the military can opener to be readily available at any time by attaching to your keys or dog tag chain, and is engraved with a mil-spec manufacturer's contract number "MIL-J-0837". The P-38 can opener is still available as a piece of military history and used by folks all around the world to open canned food, and available at Aircorpcamo.

  • The P-38 got it's name because of the length of the device is 38 mm long.
  • The larger P-51, designed for opening the large canned food trays used in field kitchens is 51 mm long.
  • MADE IN USA
