BTW, who the heck Rorion man is? You show both picture of Rorion and Bruce Lee to people on the street, lets see who is the most the most influential one..
Bruce Lee has influenced the founders of UFC and He was much bigger than UFC. Bruce knows how to use weapons too.. His martial arts also influenced modern fighting video games like Street Fighter, Tekken etc..
In my opinion, Using weapon is more useful in a real life fight incident. When you face multiple thugs or people with knifes.
