. . . . . To me, the strength of the BJD is that it is a double weapon that has direct transfer to and from the empty-hand methods. Try to use it as just a single weapon and you lose a lot of that. A single weapon method is primarily one-sided, whereas empty-hands and BJD concepts emphasize using both sides equally. This is a major tactical difference when it comes to weapons. Now the weapon-hand and the empty-hand are doing very different things and the weapon takes precedence. Movements are no longer symmetrical. The length of the weapon makes a big difference as well. In some respects, the bigger weapon can be easier to deal with than the shorter tactical folder. Movements with the tactical folder are tighter, faster, more elusive, and more changeable. These are major factors to take into consideration. So...yes....BJD is "adaptable." But wouldn't it be better to train something that is directly applicable rather than something that must be "adapted"? Or, if you are going to "adapt" things, then make it a formal change and actually train it that way until it works like you hope it will. Of course that may be exactly what you are doing.
