It seems that most of us hold the can opener perpendicular (vertical) to th e can. But as you?ll see in the video below, that is the wrong meth od.
That looks a lot cleaner. It also grabs the lid and eliminates potential cu ts trying to remove the lid. There are can openers with magnets to grab the lid, but they are messy and still pose a risk of cuts.
The lid can be disposed of by simply opening the can opener over the garbag e can. The edges are smooth and pose no danger of cuts.
The can may have some wrinkled edges, but the cut is smooth and poses littl e danger of cuts.
I wish I had known about this a long time ago. After cutting myself many ti mes on sharp can lids, I am always terrified to open a can. This solves the problem.
