Once there was a guy who had a bounce free
hammer and I asked how it worked. He explained
the little balls going up and down. I was
terribly impressed by this. But then one day
I used one myself and slammed it open and could
see it all first hand. It was still a good
answer but quite possibly that's the way he had
found out as well. Somehow took the magic out
of it.
