Practical Tang Soo Do - “Because This Is Kata (Hyung) It Has To Look Good”

“Note that in actual combat, you should not strike with your left elbow, but thrust with your left fist. Precisely because this is kata, it has to look good, and so that it conceals (the real combat applications).” ~ Motobu Choki, Watashi No Karate-jutsu published in 1932 (translation by Andreas Quast)
