This "Tactical Blade" looks hokey.

Plenty of places for Mr. James Williams to have his wrists cut in this video. Also, any strong resistance vs a long gun will not end up with the good guy tossing the bad guy effortlessly. The actors dummied for the instuctor in my opinion.
It is one cool looking video though. I just think is gives budding practitioners that they don't have to sweat, bend their knees, do cardio, strength train, or feel some pain when they train.

Compare this to the Atienza's Mass Attack Clip. That is chaos, but it is a METHOD, of dealing with chaos as well.

Yeah, this is the Systema guys again.  While the founder is a martial arts genius, all of the demos in this video give me that "aikido demo" feel in which the demo would never look as beautiful unless your opponents are from your own school.
