Mike Janich of Martial Blade Concepts shows the Master Technique, the three basic moves that lay the foundation for effectively using a knife for defense. Notice there is no mention of stabbing. Good knife fighting is about taking away the attacker's ability to fight. That means cutting the muscle groups that allow your attacker to wield a weapon or move effectively.
