Weight = Body weight + hips Speed = 30 ft/second Hardness = Does brick walls Bit of a willy wave, and nowt to do with mining, sorry. Its a genuine hardened fist from ''old school'' karate. Striking surface is the two big knuckles which are very hard. Through continued pounding something happens to the bone and it becomes a bit like iron. No kidding.
