Kuhn Rikon Safety Can Opener
No sharp edges
It may be a terribly long and unwieldy name, but the Kuhn Rikon Auto Safety Lid Lifter ($18) is far and away the coolest can opener I have ever used.
Why? The blade cuts into the can *below* the rim so the lid never falls into the food, and the blade doesn’t touch the food either. You can use it to open “pop top” lids as well. A can opened with this tool will have no sharp edges. Apparently, it works for both righties and lefties (not tried). Best of all you can challenge your friends by handing them the opener and a can and watch them figure out how to use it.01/31/19
