I always liked the P-51/P-38 style. Used to be really fast with them. This seems like it would be much easier on the hands and wrist. The last P-51 I had died prematurely as well, but I suspect that was from additional wear being kept with my keys.
I find they last for a number of decades, and still carry on and on.
EDIT:
On the other hand, things tended to be better made, decades ago, when I got these. Maybe the quality of tin openers has gone down hill, in recent years. If I remember correctly, I bought a spare one, for that very possibility. In case my current one, eventually breaks.
I'm a bit suspicious of anything with plastic aside from maybe on the handle at this point. Even the metal seems to be lower quality on newer can openers. They're just such ridiculously simple tools that used to be made well it's really a shame to see. The last one that failed appeared to be all metal, but the gear shaft went though a plastic piece. The plastic broke and it left the opener unable to bite cans.
I think I'll go ahead and order both of these and see. Thank you both for your suggestions.
