In a few years, the choice of products I found useful for me, that are different from what other people that have, like, two hands, have boiled down to a few. It may be of interest to list these.
This jar opener is surprisingly simply made. It features a saw blade mounted to a plastic triangle. So far, however, all jar lids surrendered to my opening attempts and so I would without reluctance recommend this one.
The wall mounted bottle opener is definitely the best option in my experience.
This pocket type bottle opener also works very well. It may be better than the wall mount when I expect the bottle to sputter some foam.
And before I get "creative" when, say, there is no bottle opener in a hotel room or such, my prosthetic hand usually features one of these ring type openers.
As I previously posted, I use Lock Laces. I tried a number of other options and not only are these fast to use, they also allow me to firmly set my laces to a "somewhat relaxed" width which normal shoe lace knots do not allow as a feature.
Boots (slip on)
I wear these slip-on boots since decades. They are very useful and comfortable, durable and usually relatively presentable (gotta shine them though).
Real nail file
All other options to cut finger nails suck. A real file works best.
