I used it well into my adult life and never knew what it was actually called.  Was in a army surplus back in the 80s and they had a box of hundreds of them and it was labeled, only reason I knew what it was actually called - we just called it the can opener.

Also have used a field knife and once a flat head screwdriver and a hammer when it fell out of my pack one year and started putting them on zippers and carry more then one.

I watched a friend almost cut his thumb off doing it with a knife once so got him a few for his Christmas stocking that year, and try not to resort to the drastic if it can be helped.
