I was very interested to see a non-cutting can opener but they don't exist. They all cut metal. None uncrimp/separate the seam, its too much work.

See how double seams are formed

All the side-openers cut the outer most seam at 90 degrees, so when you lift the lid you're left with a rounded edge, put there by the double-seaming process.
