In this 9th edition, Master Pantazi focuses on using Kyusho points against knife attacks through two main methods of defense that we can train: 1. Arm destruction, indicated for those who prefer working from a more defensive approach, where the main objectives are the nerves of the arm to cause dysfunction. 2. Attacks towards the source of aggression, avoiding the arm and the weapon. In this method we show ourselves totally offensive, and we instantly attack head points to get an immediate physical dysfunction. A simple, efficient, and devastating approach to self-defense, whatever martial style you practice.
