As a guess;  the pendular moment ( at the right weight and length ratio, a 
pendulum needs little energy to keep it swinging) has both handle length 
and head weight as  the determining factors.  Thats part of the reason why 
one always ends up instinctively choking up on each hammer 
handle  differently...( determines the length of the pendulum) Here the 
frequency is real low ( strokes per minute).
   The other frequency in question  ( I'm proposing, dont blush) is how the 
handle vibrates on impact...sort of like a guitar string.  The wave motion 
of the vibrations is greatest at some points down the length and least ( 
the null point) at others. The speculation here is that  you want to grip 
the handle at the null point.
So ideally, a great hammer would have the handle length   where it is 
easiest to swing and the null point  for handle vibrations  coincide..
Is this right?
