What we found is that many styles teach kata applications or "bunkai," and teach concepts such as one-step sparring. These actions do what I call "making sense of things;" in other words, they teach you how to use the techniques that are learned in the katas and in sparring.
Why not do the same for weapons? Get a training partner and do some one-step sparring drills with a bo staff for example, or mix it up with a bo versus the sai. Afterwards, you can progress to two-, three-, and four-step sparring. Another great drill is to take a section of your weapon kata and turn that section into a three- or four-step sparring drill. Believe me, as a result you will learn so much more about your weapons techniques.
