Six years on, I just deployed the last of the aluminum spares from the original CNC project:
I swear the cutter gear on the left does not show that rust in person!
This can opener has a slightly larger bolt than the previous ones, so I embiggened the hole with a step drill:
Having run out of aluminum gears, I’ll be forced to make a hob to make a steel gear. Drat!

I was thinking more like this type of pull-tab can https://www.researchgate.net/figure/Food-cans-with-and-without-the-easy-open-pull-tab-on-the-top-cover_fig1_228342418
Of course, when the tab breaks you have to revert to hand tools or application of blunt force. I believe the risk of this scenario is inversely proportional to how hungry you are
The major opener use around here is for canned salmon, zero brands of which have E-Z open cans, so I think we’re sunk. Sardines, now, those have zip-top lids, but, after a few trials, she’s no fan of sardines.
If I had to eat canned anything, I’d be way skinny; there’s a time for every style and that ain’t mine.
Canned salmon!? Dream on… ;-)
