Do you have a site or reference that shows how Sigung ties his belt? I liked the look for grappling, when I don't want the ends hanging down. It was clean and better than my just tucking it.
This will be rather hard to explain....
Ok put on your belt (wrap or whatever) just as you would normally, and stop after you fold the top belt under the bottom two layers.
1) Take the end of the belt that is sticking out of to top and loop it under the top layer so that it points downward, but to the inside of the end of the belt that is sticking out of the bottom. Do not tighten this yet, you need a loop.
2) Take the end of the belt that is sticking out of the bottom, and pass it through the loop created in step one. Pass the end of the belt through the top belt layer so that it is point downard.
3) Pull from both ends to tighten the knot.
4) The belt ends are now sticking downwards from between the top and bottom layers of your belt. Slide the belt ends between the two belt layers, and voila you have a belt that is knotted, but has no visible ends.
I really like this knot system, it almost never comes untied and it presents a very neat image. I also like that it hides the belt ends, so that the rank doesn't show, but that is my personal thing. I usually wear my belt that way now, it is just a personal preference. Thanks to Mr. Sipes for showing me this knot.
