Hello I'm trying to find out how many and what kind of techniques there were in Taekwondo, at about 1940-1960; specifically how far it had developed from Karate-do at this early stage. From what I've read, it seems Karate-do and Taekwondo were virtually identical as late as 1968 (says Sihak Henry Cho). That seems a bit late, but from what I can tell Karate-do and Taekwondo were virtually identical at least through the better part of the fifties. I'd like to know when, exactly, the circular techniques became part of Taekwondo. If anyone can tell me, or tell me where I can read about it, I'd appreciate it very much. Thank you, Jester
