Hello, I'm new to nunchaku and recently bought two pairs (1 foam, 1 wood) so that I could try and learn how to use them. I was hoping for some help in adjusting the rope length in my wooden nunchaku. The foam pair has chain links, and the length is great (its as wide as my hand), but the wood ones have a very short rope (about half the length of my hand) and I'd like to adjust them, if possible. If anyone could help me out, I'd really appreciate it.
