This book is not for beginners. Nowhere does it explain the basic grips nor how to flip the sai - the single most important move to know.
The stories are interesting, and the kata can be worked out from the pictures (although there are some photos which don't match the description). There are also a small number of defence moves against sword but nothing is shown of defence against other weapons such as the bo, jo, etc.
If you are already familiar with the sai, and you would like to expand your knowledge of kata then this book may be useful.
This is a very good book, detailing history, techniques and step by step photos of a couple of sai kata.The book is written in 'laymen's terms' and is very reader friendly.I would recommend this book to anyone wanting to learn or expand their knowledge of saijutsu and Okinawan kobudo.
