The best MANUAL can opener on the market is available at the Family Dollar Store for about $5. Black or Red, your choice. Works flawlessly on any can, even Spam types, is easily cleaned, easily disassembled and tightened up, and will be the last one you ever buy. Get 2, one of each color. You do however have to have some hand power to work it.
This is it right here: https://www.familydollar.com/family-chef-deluxe-can-openers/FD621016They have it listed for $3., and now is in red and blue, not black. Has 2 negative reviews by what I can only surmise are people no smarter than a can opener. Buy one for $3 and check it out, see if you're smarter than a can opener. lol You can thank me later.
We have one like the picture above. It doesn't actually cut on the inside of the rim like normal can openers, it cuts the actual rim. Poorly. After about a year it's gone dull and barely cuts. I usually let it go around the can 4 or 5 times, then still have to pry with a butter knife to get it open. When the wife isn't looking, I just use the can open on my swiss army knife. But she doesn't want one of the good electric ones you mount on the underside of the cabinets, or one of the old fashion hand crank kinds that always works. So we have that thing above and I hate it. Batteries last a long time though.
my P-38 (from '66) still works like a champ; I give it a quick touchup with a stone every so often
Picked one up at an estate sale for 2 bucks, took a chnge on weather it would work with new batteries. turns out the beatteries in it were good and I just wasted $2 on junk that did not function.
Kinda looks like mother's (other) little helper.
I bought a stainless steel manual can opener from Williams Sonoma (leaves no sharp edges). Maybe Zyliss? I bought it in the 90's for about $25.00. That was one of the best kitchen tools I've bought as far as ease, cleanliness and lasting this long. It is still in perfect working order and looks brand new after all these years.
Doubles as a dual-control dildo.
Can opener!! Just scrape the top of the can on a concrete block until you wear down the metal.
