You could probably sharpen the can opener by using an old metal file, and run it along the inside edges of the sharpener blade. My husband has purchased a lot of old tools at estate sales and some garage sales.

I've read that you can sharpen scissors by cutting up a sheet of sandpaper, very fine grit, I assume. I wonder if that would work with a can opener?

I fold up a small sheet of aluminum foil and run it through the blade a couple of times. It seems to do the trick.

For about 50 cents you can buy a new blade at an applicance repair center. Or maybe it's 75 cents by now....
