Nogent Super Kim Can Opener

Unlike a typical can opener, which often requires a death grip on the handles to pierce and hold the can, this one is easy to use.

It has no handles, and in place of the usual cutting wheel, it has a triangular tempered carbon-steel blade that automatically engages as you turn the cushioned butterfly-shaped crank, piercing the top of the can and locking in place.

The lid is quickly removed without a struggle, leaving the open can with a safe, dull upper edge. It even works on rectangular cans with small-radius rounded corners, which are notoriously tricky to open with a regular opener.
