what do you mean by bladed motion?
This concept is taking the fact that you don't fight someone at their game. In one sense we teach to avoid trading blows in long or kicking range. This tag game doesn't last long and the end is predictable. So the option is to move. If you watch someone spar who is a kickboxer. Thy simply move and train to avoid the threat of the kick.
If you train for the reality of the blade then you learn to move to avoid being cut or stuck. The footwork is different the hand movement is different and sensitivity is much higher. It mimics more "cat like" motion. movement is less wide based and spread and quicker utilizing angles and better penetration.
Thus bladed motion is
1) moving as if there is a constant threat of a blade
2) moving to better utilize your weapons while avoiding their's
When weapon sparring the best concept is to keep in mind that it is better not to ever cut them than to get cut once yourself. Using this concept, we attack very differently and more surely.
How do you get it..............Weapons, Weapons, Weapons, Spar, Spar, Spar.
One time I read an article by an Instructor who stated that they too did weapons but they simply used their usual punches, blocks and kicks in the same way they use their weapons. They punch with sticks.
This is not going to do it. You really have to have a strong weapons base to accomplish it. Learning a few simple drills with weapons will not do it and nor will simply punching and blocking with sticks. The result however is unreal. Personally (and I am biased) I would suggest an FMA to gain this.
Hope this helps.
