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.
