One of the other BBs who teaches in my area teaches weapons in addition to TKD. He had a IV Dan in... darn, I tried to remember; it was Japanese (he said we'd learn 1, maybe 2 kata over the course of the 8 classes) and both terms started with "k" (sorry, I'm pretty tired now) - anyway, he taught us several basic strikes and blocks, and 3 sets of movements, which hopefully I'll still remember tomorrow. I haven't been a white belt in a long time - it was a lot of fun!
