I've just finished my own hi-tech version.http://Shaft is steel, the head is aluminium and the faces are delrin.Overal length is 12.5", the head is 2.5 diameter x 3.375" and the faces are 3" diameter x 0.625" with a 3.5" radius front.Weight comes in at a massive 3lbs 7ozs, this is a mallet for real men only
By the way how much did this cost?
