I have a par of Sai that Yasuzato Sensei gave me in 1965, Sasebo Japan, the Sai set was one custom made for him. Yasuzato Sensei was teaching on the navy base in Sasebo at the time and I was one of his students. His system was called ShoBuKan,Okiwian Karate Do League. He was the grandson of Azato Sensei, one of orginal creators of karate systems as we know it today. Anyone have an idea of the Sai sets worth, also I have never been able to find out what happen to Yasuzato Sensei school in Sasebo, or his system. Anyone know. Thanks Bill Ennis in Califorina
