Those are really cute! I have never heard of that type of can opener. Is it manual or electric? I have a lid ornament that I made using the actual lid from a jar of spreadable cheese, but soup cans are definitely much more common in my kitchen. Are the lids sharp after they are cut off?
I have one that is manual. It's really easy to use. I don't remember it being expensive either.
This is such a cute idea!
