Sliding weights

There is a tool used in orthopedic surgery for driving and extracting nails in bone. The concept is simple, but effective: the tool's head is placed on the nail head, and a sliding weight is forceably impacted in the desired direction. Forward to drive the nail, back to extract.

As with Jim's observation, this is not directly relevant, but may be edifying.

Jim, thanks for checking Stone's glossary for me. Now I'll have to figure out what stray memory I was thinking of. Possibly it was a sliding sleeve on a spear (for the forward hand, so you don't sand your palm off jabbing with the spear). Otherwise, I agree with you about the value of that book. I discovered my parents' original copy as an impressionable pre-teen. Now I'm here. Go figure.
