This is a Silat Style from Brunei. Its a Weapon-oriented System.
The initial unarmed response are the drills used to hone reflex and sensitivity, there are only 3 basic interceptions and from that "base-template" defensive & offensive entries on any attacks armed or unarmed are gained.
You learn, you understand, then you understand why you learn.
ITS THE MOVEMENTS THAT YOU CAN'T SEE THAT MAKES THE TECHNIQUES EFFECTIVE.
The movements and skills shown are NOT CHOREOGRAPHED.
Novices are taught to develope thier unarmed single knife awareness, reflexes, correct responses & sensitivity in thier initial training. They are taught to read body moevements through understanding body-mechanics.
