Probably unconventional now, but one of those old can openers. Not the turning ones, the manual single-piece ones. Every can opener I have had dies after a year or two, but this one has been going strong for like.. 50+ years.
Boy oh boy have I been waiting for the opportunity to plug my favorite can opener. It’s a “turning one” as you call it, from a company called OhSay. American made, and built like a brick shit house, I have no doubts it’ll outlast me. Google it, I think they’re like $15-20
Hell yeah, I’ll give it a look. I’ve almost made it a hobby to research the shit out of the most durable and long lasting items I can buy, and things that are capable of being maintained or repaired since I’m kind of a tinkerer. I also buy American or union made whenever it’s an option.
