Sorry about your boo boo. Throw that can opener away! Tupperware has a very nice one, lifetime warranty as long as you do not put it in the dishwasher.It cuts the rim & has a little beak to take the lid off, it's R or L handed, very easy to use. Before I purchased this one , I was buying one every year sometimes more and had so many nicks and cuts. This one solved that issue.I have had this one 3 or 4 years. love it, comes in black or white i think. Just think positive thoughts and wishing you a speedy recovery. :-D
