Now, for swiss army knife can openers:

The blade portion of the can opener is on the front, so it seems to work better turning the can in a clock-wise direction. Still holding the can in the left hand, can opener in the right, placing the opener on the right edge of the can.

Basically, I always hold the can opener in my dominant hand, can in my non-dominant hand, place the can opener on the side that is easiest to reach with my dominant hand, and turn the can towards the sharpened edge of the can opener.

Now that makes sense. Thanks for that.
