Having killed several wall mounted tin openers in the kitchen I took the opportunity to get a NoS Bonzer catering can opener from a army surplus stall and fitted that to the counter top. Works a treat and after about 10 years of hammer I've still to open the spares pack that came with it.
This sort of thing

Out in the sticks I use a SAK or one on a Leatherman. Only time I've chopped myself is when my minds wandered while opening a Bully can.
As it happens I sort of collect tin openers, they are often mixed in with the tools on carboots and rarely cost more than a quid or two. Herself has bought me one from ebay ( nthe fish shaped one)for a present and a couple ive got from antique shops for about a fiver. Normally they are in pretty poor nick so i do them up to be usable.
Theres plenty of types to find yet. I'm especially keen to get some of th early ones especially a Timmins leaver knife and a Yates patent.
A awful lot of tripe is written and repeated on the internet but I stumbled on this excellent potted history.

New to me is the concept of can middens

Which are diagnostic with regards to how they were opened back in the day on the frontiers or by expeditions.where cans were first used on a large scale.
I'll get my coat.
