I used to cut myself with stunning regularity while feeding my cats at the crack of dawn. Maybe it was just too early for me to operate items with sharp edges. I finally realized that safe can openers exist and bought one here about nine months ago. Boy has it ever helped. It is super easy to use, opens cans like nobody's business, and best of all I have not had a cut since I bought it.
It is well made, has very comfortable grips, has not jammed once, turns easily (unlike my old can opener which would get gunked up with whatever's in the can and proceed to grind it's way around the edge), and has little pincers so that lifting the lid is a breeze. I love it, my cats love it, my fingers love it, my cans love it, and I cannot recommend it enough.
