When I was a kid we had an opener with a corkscrew like that. I doubt it was military issue, maybe the source for the military later on.
I had a boss at Boeing who was a Colonel in the reserves. He brought is some MREs he kept in the trunk of his car for emergencies. I opened a foil pouched brownie and as I'd expect for a brownie with miles on it the surface was crisscrossed with cracks. What I didn't expect was the cracks were lined with white. Close examination showed it was crystals of sugar I assume migrated from the brownie... or cocaine for morale.
