These pics are the result of an attempt by a grappling trained police officer to deal with an assailant armed with a knife. They are quite graphic.
Obviously submission, regardless of method, is the ideal place to put an attacker who has a knife. This can be done via strikes or chokes, locks, holds, etc.
Intercepting an attack can provide split seconds to either fully engage in a grappling counter, or a striking counter.
A striking counter can attack weak, soft structures such as the eyes, the throat, back of the head. (And yes, if people can spend hours perfecting anything, they too can get pin point accuracy using simple training methods: non-rhythmic focus pads, a ball on a string, a double end boxing bag, etc). Once eyesight or breathing are deeply disrupted, control and restraint can be exercised.
A grappling counter can restrain the knife hand and move through to various limb and neck holds including full out takedown. Once control is obtained, striking can commence. One could suggest that within striking range is within stabbing range and grappling range...
The structures of weakness cannot be trained to withstand blunt trauma and force...Can one continue to fight while blind? While unable to breathe?
The relative leverage and strength of a man can be beyond what appearances suggest as well as the factor drugs can play in enhancing strength: ie cocaine, speed, PCP, etc.
What is your line of defense? Level of preperation? Perceived opinions on this topic? Disputes to the outline above? How does this relate to the responsibility of a police officer (To use restraint and submission) versus that of a citizen (Not in the public eye under scrutiny of ethic committees, and less likely to find criticism for using foul tactics)?
Is a combination of the two ideal? Or does one approach favour your style and personal attributes?
Does your art deal with interception using forearm strikes, restraints? Obviously weaving, ducking, movement play a huge factor...but covering up does not.
