Much has been written, filmed and taught publicly in Kyusho recently, mostly on the anatomical targets and the affects. But nothing has been written on the weapons of ancient times to best attack them or the way in which they are actually used.

They forged them over time into solid actual weapons by what we would think as extreme and possibly foolish methods. As an example the fingers would be conditioned first by grasping heavy pottery.
