Honestly, I've never thought about donating them. I wouldn't know where to begin. I always let them pile up, fill a couple of junky plastic tool boxes, and sell them as a lot at my yard sales. I never have a problem selling them.
If we are able to do "dibs", I want dibs on the hose clamp-off pliers.
Possibly the 2 or 3 jaw puller(I cant tell how many jaws it has), the pulley puller that uses bolts and the metal strap wrench.
If you have flare nut wrenches I may want those also...
