Jay, I was amazed when it was showed to me, right before intervenining my friend saw me put the head of a hammer similar to the one in the video in a vise. I was reaching for a large sledge, I was going to show the handle "who was the boss".
Like you said, light little taps "jumped that handle" into the unsupported head. For a logical thinker it made no sense.
I was hoping this thread could get some traction, I bet you could fill an encyclopedia with your secrets.
