Summary

In Part 1, we saw that:

-71.1% of knife attacks are led with the free hand and this dramatically alters the dynamic of the attack along with your initial reaction.
-Most knife attacks are ambushes, not duels. Attackers rarely brandish the knife; they keep it concealed until the very last moment.
-70.6% of knife attacks are launched within 3 feet of the victim
-Knife attacks are fast and furious, often resulting in the victim falling on the ground.
-Knife attacks don't last long, avg time is 23 seconds but 50% of attacks last 14 seconds or less.
-Knife attacks are more often performed with quick, short repetitive stabs at different angles. There's usually a first, very aggressive, wave of stabs (5 to 10).


In Part 2, we covered:

-Avoidance and Situational Awareness
-Knife awareness is key
-Escaping should be the priority
-Compliance and its limitation
-Weapons and the issue of deployment


In Part 3, we highlighted a number of principles to remember:

-you need to get control over the knife-wielding hand (or arm)
-grabbing the knife wielding hand is always preferable to parrying/blocking
-close the distance quickly and smoothly and stay as close to your aggressor as possible
-maintain forward pressure and
-take control of the knife-bearing arm as soon as possible
-shut down your attacker aggressively
