lord, why would anyone put an instructional on youtube, nothing but smartasses and know it alls respond. Incidentally, the "ninja" claw looks and sounds ridiculous but I know for a fact that using your fingers instead of your fists in a street fight can have many advantages, the main one being you don't break your hand. clawing and eye poking is the quickest way to handle a situation, if it's life or death or if it looks that way, I see nothing wrong with taking an attackers eyes out. It's not skillful or pretty but it's simple and works well.
