Well, my GM and his teacher (1950’s) simply used boxing as open hands and used the concepts of sinawali and hubud opportunistically when the opening revealed itself. The same with breaks and locks. We learn a lot of stuff, but softening up the opponent first is key. With the knife we train NOT to duel or chase. Stopping the weapon abruptly, creating as much damage as possible, THEN break, lock, throw, etc. What is the difference between gunting and the boxing split entry? Just movement in a series of other movements.
