“I have had contact with Samir’s work personally and I can attest that it is really very serious and well structured. In addition to a thorough research, involves extensive analysis and a lot of pressure testing. Besides he has detailed me the process, I could feel it in practice, that is the best proof you can have. I have always been a student of karate and I don’t convince myself easily. I follow the work of the well-known names of practical karate, but I can say that I have never seen a work so technically accurate, tactically correct and at the same time true to kata.” (Puro Karate Blog, Associação Karate-Do Tanaka)
