I save food cans to be used to store things like screws, nails and other small parts on racks that I have built in my garage.
When using cans that have a conventional top that is opened with a can opener like this:
I end up with a very nice top edge of the can that is easy to get parts into and out of. Here is an example of a can like that:
Unfortunately more and more cans these days have this type top that is removed using a pull tab:
The pull tab cans end up with an annoying lip remaining around the rim of the can as you can see here:
The typical can openers that I have tried are not able to cut out this annoying lip because the cutting wheel on the opener is unable to reach down far enough to engage the lip.
My question here is looking for how to conveniently remove the lip in a manner that leaves a nice edge like what is left on a conventional can after opening?
The method needs to be easy to use and not leave sharp edges. I have dozens of these annoying cans and would like to make it so much easier to get parts into and out of the cans.
