Knife assaults can be extremely dangerous and it is best to avoid them if you can, but sometimes that is not possible. Carrying a firearm can help to equalize the situation, but it is not a panacea to the problem. If you cannot get to the weapon then it does you no good and at close range a knife usually has the edge (no pun intended).
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.
The drills and techniques in this book are taken from the Southeast Asian martial arts of Silat, KunTao and the Filipino arts of Kali and Escrima. These arts are known worldwide for exceptional blade skills.
This book will help you to become familiar with knife attacks in order to de-mystify and take some of the fear away. If you understand how it can be used for an attack then you can begin to understand how to apply a suitable defense.
