Koryu.com has finally released the all too expected book on Tenshin Shoden Katori Shinto Ryu written by Soke Risuke Otake. For a long time, "The Deity and the Sword" has been listed for up to USD500 in some online stores, so for all of you that didn't want to spend that lot of money this is great news. This one-volume 336-pager is based on the earlier 3-volume work, reedited and redesigned, and for a much cheaper price.
This book contains a lot on history of the School, the techniques and the strategy for which it is famous. Some extra information about the more esoteric principles (such as the kuji in) can also be found in this great work.
