I like to use the standard crank can openers but they always wear out quickly and I had to buy many during the years.
One reason for this is there are no standards for the rim of the cans: chime and thickness.
The pop top cans leaves a sharp lid and a rim around the inside that gets in the way of emptying the can.
I made this short video to perhaps help others that have the same problems I do with opening cans.
