I have recently run across some DVD's by Sang H. Kim from Turtle Press regarding the stick fighting part of his Junsado combat system. Does anyone know if there is in fact a system of stick fighting that is indiginous to Korea? Do you think he made this system up himself, or is there in fact different styles of Korean stick arts out there that I am un-aware of? I am wondering of he took some Filipino styles, and modified it. In his double stick system, he uses a reverse grip in the subordinate hand. Let me know if you know anything about this...Thanks.
