What is the main difference between using empty hands vs weapon forms in Wing Chun? It’s not so much about techniques, but about the concept of CENTER.
When using empty hands we chase the CENTER but never the limbs.
This includes Arm Breaks, we only break it when it is given to us, but we should never look for the break or chase the limbs.
When using Knives, we do the opposite, we break the CENTER rule. Wing Chun breaks this rule on purpose.
We chase the limbs because of the nature of the short Wing Chun Knives going against a much longer, heavier, slower weapon ie. swords, spears etc.
