Thought I'd take this discussion out of Anthony's as it was getting long and of topic.
There apparently is a new Kata under development in Okinawa. Master Takara is still working on it. It will be for advanced ( Godan & up ) students. From all I know, it’s got some elements from Sanseiryu in it. There are about three people in our dojo who have seen it and have worked on it a bit.
Bill, as far as the secret handshake, I have not been privileged, but I heard that a non OKK student tried to pass a poor imitation off on an OKK master. The poor kid now goes by the name “Lefty”. Of course, I can’t verify that story.
