Ordinary wheel-cutting can openers get used wrong - they should be cutting the side of the can and not the lid, with the knurled wheel flat and pressed against the rim of the can.
No sharp lip, and you don’t need to fish a lid out of the can. Downside is you can’t use a lid cover to “save” the contents if you don’t use them all.

see, i’ve tried using them the “right” way, but i’ve found that i’d rather have the lid be sharp than the can most of the time.
