Now to be able to use it, you spar against knives, or Escrima sticks or Japanese Bokken or the Chinese spear or the Chinese staff (from any art). That gets you the proper positioning, awareness, timing, speed and power. The knife provides extra footwork needed to deal with highly mobile opponents or opponent's good with kicking. Hundreds of hours have to be put in so this is just the first step. The form doesn't look like much and every lineage has their own form because the form was not really taught.
This butterfly form in my opinion, is very ROBOTIC it should have more style FLAIR. I know your doing correct, Nevertheless- New form should be developed.
