A truly comprehensive guide to the reality of the blade! 

Edge is a combination of years of practical experience and knowledge, presented in terms and skill development methods that will prepare you for dangerous events. An excellent addition to any library on combatives and fighting, this will enhance skills for not only professionals but the average person as well!

 It was very informative to see the Relaxation to Power idea applied through so many training points – from simple exercises to effective ground work and strong punches, unexpected to the partner. 
It was nicely shown how to locate areas of tension and how not to overpower the opponents physically and yet, easily overcome their resistance. Great job, Ryo! 

 The original version is in my top 10 favorite books on martial arts so I had to get the expanded,enhanced version.

The knowledge and wisdom shared in this book definitely gives you a great understanding of The System. Even if you don’t practice this art in particular, the information presented here is priceless and a great add on to whatever art you enjoy. Thanks Mr.Vladimir Vasilev for the reissue. I’m ordering it now.
