Okay, I'll play.

I have no idea what the hell a fliptop can opener is, but I dearly love my Pampered Chef Smooth-Edge Can Opener. It doesn't cut through the lid of the can. It cuts through the side of the crimp that holds the lid onto the can. It leaves no sharp edges for you to slice your finger on and you can even put the lid back on the can after opening. Also, the cutting wheel never touches the food, so it doesn't get all gunky like most can openers do. When I got it as a gift I sorta went "What the fuck?" but I'm now officially in love with it.

Simple minds, simple pleasures...
