This question comes up in every knife thread, of which there are many on this forum.

I use a small multitool (Leatherman Micra, 1.9 oz.). I need the pliers to compensate for lack of gripping power in my fingertips. More than once I've had to thread a strap through a buckle and can't grasp enough of it to pull through without those pliers. I also use the pliers as a pot lifter. The tiny screwdriver tightens the screws on my glasses (which I have to do every few days). The regular screwdriver is for pushing and prying. There's a small file which is great for finger and toenails (my nails split and break easily--they always have). The item I use the least is the blade!
