I do not use lots of canned food because most are heavily salted. However, I love to make homemade spaghetti sauce and chili which require some canned food. I make a big batch and freeze it in individual food containers that can be heated in the microwave. Since I cannot make food taste better with butter or cream sauces I add lots of veggies to these one pot recipes.
I use an electric can opener made by Krups that uncrimps the metal rather than cutting it. This leaves a smooth edge so the top can be put back on if you want to use the contents later. The photo on the right shows how a right-handed person holds it while the photo below shows how my left hand holds it so I can see what I am doing.
Short cans do not have the clearance I need so I put them on a food storage container. Since I do not open cans that often I have trouble finding the exact angle the opener requires. I have to try two to three times before my wrist remembers the correct angle. I know when I get it right because the noise changes from a high pitched whine to a low pitched growl. The only time this can opener has let me down is when a hurricane has cut my electricity.
