A great companion to the book!
It is difficult to find a comprehensive book on knife training and defensive moves outside of military manuals and a few martial arts books. Most simply show you techniques, but never go into drills or concepts. Techniques are fine, but you need to be able to adapt to an ever changing situation. No two attackers or situations are ever the same, everyone reacts differently in a hostile environment and you need to be prepared.
Volume 1 goes into the Angles of Attack, Footwork (4 types) and Evasion.
Cross Body Blocking with Special emphasis on the Straight Thrust.
Grabbing, Arm Breaking, Tapping and drills for working on the Focus Pads
