Actually, a great patent, this can opener. The corners of the box have actually after opening any sharp edges, which not only benefits families with children, but also stray quadrupeds, who otherwise like to pull himself up in landfills times gruesome cuts on half empty discarded cans.
The only complaint is that the mechanism requires a little effort. My friend who is actually not squeamish otherwise (Handyman daughter) that barely unpacked. Really with the device it but like - now I just always open the cans.
