Just a couple of questions: 1. Could someone list and describe any martial arts systems where two swords or sticks are used together? (I've practiced Arnis, and I already have a separate thread about Nito) 2. What sword fighting system was used with the Green Destiny in Crouching Tiger, Hidden Dragon? I ask this because it's the only time I've seen a double edged sword used with 1 hand. Please forgive my ignorance Thanks in advance, Mike
