[TheForge] Blacksmith Sledge

[Peter Hirst]

As someone pointed out to me recently, hammer velocity has the most to do 
with it.  Basic physics: E=M x Vsquared.   It means that energy delivered 
increases directly with an increase in mass but exponentially with increase 
in velocity.  Twice the weight, twice the energy.  But twice the speed, FOUR 
times the energy.  Three times the speed, 8 times the energy.  The kid with 
the 12 pounder probably was out working the LG 25 blow per blow.
