An excellent book from a historical point of view as well as techniqual. I enjoyed it immensely. My only disappointment was in the Kata section. The reader sees no transition from technique to technique, only the end product. I believe in doing so, the book would have been much larger. In other books they may take half a page to a full page to demonstrate each techniuqe. In this book, each page may average 10 techniques. On the whole this is an excellent book and a must have for any serious Karate Ka.
