I harken us back to the day of the C-Ration. The days when hungry GI Joes had to open their canned pork-n-beans with what was arguably one of the Army’s greatest inventions. The P38 Can Opener.
It’s official designation is ‘US ARMY POCKET CAN OPENER’ or ‘OPENER, CAN, HAND, FOLDING, TYPE I‘, but is almost always called a “P-38” which it supposedly acquired from the “38 Punctures” required to open a C-Ration can.
I have carried one of these little gems on my key-ring for years and have an extra stashed away. It’s well worth the buck or so to pick one up.
