We have a Chefmate safe cut can opener. It is a manual opener that cuts in from the side of the lid instead of the top so it doesn't leave a sharp edge. That was actually the primary decision point in picking the opener.

It has held up pretty well so far (about a year) and is easy enough to use that we gave up on the electric can openers after going through two of them in about 6 months.

No affiliation with the company, just a satisfied (so far) customer.
