So Jutsu	Rokushaku Bo Jutsu	Knife & Pistol Fighting

Those books are really interesting with all levels of the Yari (So) - Bo Jutsu & also the Knife and Pistol Fighting Techniques. With some knowledge in handling pole-weapons, it’ll be easy to learn and apply the many techniques shown in those books. Apart from that, it also contains a lot of Densho (scrolls of transmission), which makes it an interesting read for martial historians.
