Same with me, most all those I'm associated with no one over 3rd degree has stripes on their belts, just the 1st-3rd dans[/.quote]
There are a lot of practitioners out there who have a lot of stripes on their belts, more than three. usually their dobok are also decked out like a christmas tree as well. I tend towards a plain patchless uniform. I have my name embroidered on one side of my belt in hangul and the name of my school and association in hangul on the other. but i don't have any stripes embroidered on my belt and none of my dan holder students do either.
Historically, names were written on belts and dobok because the students would leave their uniforms and belts at the dojang, and it was a way of knowing which one was yours. no one had stripes or anything other than their names on their stuff. It is the same way that high school kids write their names on their PE clothes, so it doesn't get lost in the locker room. In Korea, I saw many high school age students wearing their high school uniforms, and they all had their names embroidered on the front pocket.
I want to say that it was Sensei Mas Oyama who popularized the idea of putting stripes on one's belt. He was the first senior who I think did that and it was prominently displaying in his books. Him and Ed Parker.
