I actually use the scissors most often (including for nail trimming, followed by the nail file and closely by the toothpick. I'll sometimes use the knife for meal prep, but not very often. I think I used the screwdriver once, when a screw on a stove came loose (the end of my spoon might also have done the job.) I've also used the tweezers once or twice for splinters (so-so), and once to tighten a glasses screw (since I only used one tine, does that count as a full or half use?)
