This question is for anyone that can answer. I would really like to hear from some KSW practioners. I am currently studying TKD and a friend of mine is a 3rd dan in KSW. I have read (on a hostile site) some pretty harsh comments about KSW. I keep reading that KSW is NOT good for self defense. Granted, these comments seem to be coming from those who are only interested in MMA, which I am not. I have no desire. I would really like to learn it for SD purposes. Is KSW useful for SD?
