Been away quite a while, but thought I'd drop my two cents. Pretty much everything tenshinka has stated is the same information I scraped up as well, and you DO have to scrape. Remember that KSW is "based" on the three general origins of Korean martial arts (Royal court, buddist, family). Our GM didn't personally learn them this way as they don't exist this way any longer (except the buddist to a certain extent). The history of KSW you read in our books is describing the roots of the techniques, not how they were combined by Kuk Sa Nim. I usually like to think of it this way. He learned many arts/ techniques from many different masters. Others also learned similar (or same) techniques from the same or other masters. These students began combining what they felt were the best of each technique they learned. Some studied together under the same instructor(s), other learned similar patterns and techniques from others. And, as was stated, many were influenced by more than just Korean martial arts (thought I agree more from China than Japan). So, you have an intermingling of students that were combining techniques of traditional arts, basically making the first attempt at mixing martial arts. However success, money, prestige, etc. can break apart friendships/ partnerships. And ulitmately, "There can be only one" on top. So, they started breaking away and forming their seperate organizations. No matter what the actual origin is, I really enjoy my martial art of choice, and have never contemplating leaving it. The fact that I'm 14 years into it, and will begin testing for 4th degree soon and am still learning new material I have never seen before is enough to keep my interest for a long time. It's like a good book, as it keeps you wanting to know what's in the next chapter. Later....
