The only other club I have with such pronounced curvature is from the New Hebrides. It weighs 1087 kg and is 56 cm long. The stone club is 1.028 kg and 68 cm long. There must be some way of working out the relation between length/curvature and weight to potential force or something mathematical physics kind of stuff. I always tried "the dog eat it" no homework excuse. Who wants to go to school if the sun is out?
