Why You Should Learn Wrist Escapes, 2

Continued from "Why You Should Learn Wrist Escapes"

Last week, I published a post that included an Attackproof video demonstrating that wrist escapes won't cut it in the event of serious violent attack. (CLICK HERE) While in full agreement with that premise, I then wrote an article that explained why wrist escapes serve a valid purpose where less-than-lethal force is called for. (see link at top of this post)

Now, I would like to address the subject of learning and practicing efficient wrist escapes. First, if your instruction in escaping wrist grabs included any reference to "pulling against the attacker's thumb", you did not learn an effective/efficient technique.

While it is correct that the thumb is the weak link in  grip, pulling against it may not work in 5-10% of cases. You see, there are some immensely strong orcs out there with huge hands, and while you concentrate on pulling against the thumb, they will clock you with the other hand just to stop you from squirming.

The key to an efficient & effective wrist escape is leverage. If you know how to lever your way out of an assailant's grasp, your moves don't need to be fast, sharp or strong.

In the Attackproof video you see an example of an efficient (but ineffective) wrist escape. Note the victim -- how she pushes her elbow in toward her attacker.

In terms of a lever, the force is her body weight applied at the elbow through her upper arm (humerus). The thumb is the load, and the fulcrum is at the web of his thumb.

If she has a short forearm, the distance from the elbow (where force is applied) to the fulcrum may be only 12 inches. But the distance from the fulcrum to the thumb is even less -- perhaps a quarter of an inch.

Thus, if she applies only 25 lbs. of force on the elbow side of the lever, that translates to 600 lbs. of force against the thumb. Not many orcs can withstand 600 lbs. with their thumbs.

When my third daughter was about 12, it took less than 5 minutes of instruction & practice for her to arrive at the point where I could not, with all my strength, hold on to her wrist. She did not have to pull or tug; she merely leaned her elbow toward me to lever out of my grasp.

We continued the practice for about 15 minutes to neurally imprint the technique. When we finished, the skin of her wrists was all red from the friction of my grasp. The point is that I was holding her tightly, and I towered over her, yet she could easily lever out of my grip.

Now, I mentioned that the wrist escape portrayed in the Attackproof video was efficient but not effective. In the next post I will tell how to make the escape effective as well as efficient.
