I use a smooth edge one that is also portable and battery operated. It's wonderful! I just push the bottom and walk away as it "walks" around the can and stops when it's done. I think it's available at most stores for about $15.
I guess I didn't place the direct link in.. I'm sorry... Here is the page to the direct link: Military Can Opener P-38 & P-51Best Can Opener.... P-38 or its big brother the P-51... I've had mine on the keychain for about 20 years. Its always there when I need it and it has never failed me once.

Please note that I highly recommend this company and their products. Decent prices and have a great friendly staff.
Have to agree there. Only manual for me. In my experience the cheaper the can opener the longer it will work. They don't start slipping like the others. Keep one in my camping backbag, which is also my BOB. And have a few with my supplies. Going to stock up on them for barter or charity. A good ol' can opener can mean life or death for someone out there.I only use manual can-openers - none of the electric ones. I have several (in house, in camping supplies) and they are all very similar - solid construction with easy-grip handles.
