The GI P-38 Can Opener

Perfection in a Low-Tech Device

It's an unsung hero among the "Ten Essentials" for the Outdoors People of the World!

.

The hot Southern Oregon sun beat down on me that August day of 1965. I was hungry, so hungry I felt eager at the prospect of opening my first-ever box of Army C-rations. Nearby, the forest fire that I was fighting smouldered, but I ignored it as I threw down my Pulaski and ripped through the wrappings around my "ration." Inside, I was confronted with several cans and no way to open them. Then a tiny shiny metal object about an inch long fell out and into the pine needles. My solution was at hand. The perfect can-opener! No gears, no wheels, no electricity, no plastic! Elegant and perfect in its simple mechanical design and execution. Should be in the Smithsonian. These two images display my 1962 vintage GI P-38 can opener, still working perfectly after 45 years, although a bit the worse for wear. Officially, its instruction sheet called it a P-38, but in the Forest Service it was commonly nicknamed a "Church Key," which harked back to early bottle openers which accessed alcoholic and often-restricted substances such as beer! Invented in 1942 for WW II, some have called it the "Army's Best Invention," famed for its speed of can-opening, and also revered for its multi-tool capabilities, eg. it can be used as a screwdriver, a fingernail cleaner, a dull mini-knife, and much more! I read that the "38" referred to how many punches around the rim were required to open a can of C-rations. I haven't tried that test myself but it seems about right.

Sadly, since this device went mass-market, its quality has often gone downhill, and there sometimes isn't so much to admire about the perfection of the device. It seems too simple to mess-up, but I've bought some new ones from time to time at mass-market outlets and been disappointed. Perhaps the metal is cheaper and softer, but they just lacked the fine cutting abilities of the original from that old C-ration box, so my stained 1962 opener maintains a prime spot on my mini-biner that goes with me on any and all outdoor excursions!
