Title: Functions as Designed
Review: I'm still not sure how this can opener works but the rims of both the lid and opened can are indeed free of sharp edges. It's almost like the original seal is pried apart rather than cut. No matter. If sharp edges are a concern, then this unit does the job nicely. I've only had it for a couple months so I can't comment on durability. It's easy to use though. I love tools that work well. This is one of them. Highly recommended.
