Welcome to the final part of this series of articles on the Pinan / Heian katas as a fighting system. So far in this series we looked at the background of the Pinan katas and discussed that they are said to represent a complete fighting system that contains techniques for use at all stages and all ranges of a fight. We also discussed that whilst the modern order in which the Pinan series are taught is based upon the relative technical difficulty of the solo performance of the forms, the original order is based upon the progression of a live fight.
