Wife complained that she didn't like her Kitchen Aid hand crank can opener; it was too hard to penetrate the can and turned too hard.
I got out my needle file set and sharpened the cutting wheel. It penetrates a can easier now, but still turns hard. The drive wheel shaft rubs on a rubber collar that is putting too much drag on the drive shaft. I put salad oil on it, but doubt that it penetrates enough to lube the rubber collar. Maybe it will wear in with more use.
Anyway, it was the first time that I ever sharpened the cutting wheel on a can opener. Couldn't see any way that I could chuck it in a drill and spin it until it loosens up.
