How to Open a Can Cleanly

I always hate the way can openers leave the lid stuck to the can by that last little fragment of metal. I'm sure you do to. The problem is the way the can opener bends the metal when it punctures the can. Here's how to avoid it:
  1. Puncture can with initial squeeze of can opener.
  2. Open can backwards for half a twist.
  3. Open can forwards normally.
The issue, as I discovered, had to do with the shape of the edge at the puncture site. By twisting it backwards you are providing a nice clean edge to finish the opening action.
