Self-Defense - Krav Maga - Bursting
Human Weapon: This video tutorial shows you how to do the Bursting technique from Krav Maga. Your upper body, or torso, quickly is "released" from the lower part and bursts into the attacker's knife arm and upper body. The burst into the arm deadens the knife arm causing severe shock and often causing the assailant to drop the knife. The strike to the body can be directed against the neck, face, throat, or chest. The two strikes land simultaneously.
