In this second volume of his technical series of 5, Saito Morihiro Shihan completes his presentation of the founder's weapons system. Kumi-tachi, variations and tachi-dori are explained in detail as well as kumi-jo (the first 7), jo-dori, jo-nage and the beginnings of what later became the ken-tai-jo system. Again there is little text, hundreds of technical photos and a few shots of the Founder Morihei Ueshiba.
