Re:  longer screwdrivers work better

I belive that the extra torque comes from the extra
actual twistedness of the blade shaft of the longer
screwdriver sorta like a heavy book hung from a string
can help you break it.  (remember?)  try your test again,
backing out an easy screw and applying the heave gradually.
you should lose the advantage of the longer handle.  ain't
physics good to us?
