I have a question. My little brother is 8 years old and should be nine when he gets his black belt. I heard that the children who get thier black belt before the age of 15 doesnt really get a true black belt. Its black but says something differ. from the adult belts. I really wanna know how that works. Do they have to test twice for it or what? Im really confussed Anyone out there tell me how do the little ones really get the black belt????
