Re: How Shioda did (not) develop his power
Going back to one of Mike's previous posts, it is unlikely that Shioda developed his kokyu/ki through sword practice/suburi. Pre WWII uchi-deshi did little sword training. In the mid-thirties, a lot of what they did was kendo (which would not develop "sinking.") Shioda was not known as having skill with a sword. One of his exact contemporaries, Shirata Rinjiro spresented some sword exercises that he developed (quite interesting in their own right) and I heard him say in a class, "These probably look different to you from what you've seen from people like Saito sensei. Back when I studied, Osensei hadn't really developed much training with a sword." So however Shioda accomplished it, it wasn't likely through suburi or other weapons training.
