Don’t forget the can opener.
I thought about that when I was putting cans in the pack. So I selected only cans with the ring on top, I mean the cans you can just pop open.
Good point though. If the SHTF, lots of folks wouldn’t notice...
Any flat rock or cement surface can substitute for a can opener. Just “sand” the can with the crimped lid against the rock, and then “flext” the can. Eventually you will grind enough metal away that the lid will simply cleanly “pop” right off.
