The only manual can opener worth anything (IMHO) is the original Swing-Away. We use them camping and in the home. They are American made and last forever, if you don't lose them. They are getting harder to find locally with all the Chinese knockoffs. Search online, or look in hardware stores. The large grocery/big box discount only carry Chinese. I know, because I tried to replace one I had since the late 80's that I lost. A great piece of kit.
