We all know karate has knee techniques, elbow techniques, etc. However, ask people and they will tell you "the only MA that uses elbows/knees is muay thai" (an incorrect statement). Thing is, karate sparring, kumite, etc does not use knees, elbows, throws, etc, some techniques that exist in Karate but that somehow appear to be relegated to a vestigial status in some katas. How was the kumite criteria developed? Is today's karate far from its original concept?
