i just remembered reading something in the past about jujutsu in kata, or hapkido in taekwondo patterns. have any of you made these discoveries? do yall think historically jujutsu techniques were put in the kata, therefore making the jujutsu techniques official kata applications? this thought actually somewhat excites me since i love jujutsu and hapkido. it would be nice to say these grappling techinques are a part of karate or taekwondo.
