P-38 Can Opener
The P-38 can opener was used by soldiers to open canned field rations from WWII though the Viet Nam war. A p-38 hangs, at the ready, from my keyring in the event of a can-opener-less emergency, although I must confess I have yet t0 find myself in one. Another p-38 is sleeping in my camping contingency kit waiting to be called into service when there’s no other alternative. I continue to carry a P-38 even though, in a world of Swiss army knives, it is probably not realistically practical....
