The hat in question, or rather a “SAP CAP” is special. Keating himself wrote all about it:
The term SAP refers to a flexible, weighted impact device. A common sock (stocking) filled with sand is a crude form of sap. The weighted leather – flexible saps are used by some police units even today. The SAP CAP reflects this idea, but in a form less recognizable as an item of defense. And in today’s world this aspect is a real plus!
The basic idea behind using the sap cap is very simple. Reach up with one hand, grab the bill of the cap and the swing it off your head toward your intended target. Any number of angles, lines and moves can be incorporated. You’ve basically got a flexible club in your mitts, use it as such.
To put it in less suburban ninja terms, it’s basically a baseball cap filled with BBs. Cool.
The guy also sells videos of how to fight with a tomahawk. In addition to this, he’s a fan of compliant wrist lock drills that magically render the opponent unable to hit you with his other arm, as well as other crap that would only work in The Matrix.
