Speaking strictly as an old guy with a case of arthritis that’s getting worse rather than better: opening a folding knife with one hand is now impossible about half the time, and sometimes difficult even with two.

Don't know the law where you are but there are some “assisted opening” knives that are legal in Ill. that work great one handed. I used to do a lot of wiring up on ladders and they were a great help.
