Opening a can can be a difficult job if you don't have a good can opener. In a kitchen where a lot of canned food is supplied, a good can opener must therefore be present, so that opening these cans becomes a lot easier. In addition to the can openers themselves, Baking and Cooking also sells the wheels and blade separately, so that when the wheel or blade is blunt, you can simply replace it, instead of buying a completely new can opener.
