Courtesy of these, I now have a big honking bruise on one elbow and blood on my gi! (Got the side of my hand pinched in the chain at class tonight while working on wrist rolls.) I still need more practice, but I'm getting a lot better with my nunchaku.
And when I finally get this down, I will definitely be keeping my chuks upstairs at my house. Can't you just imagine the reaction an intruder might have to seeing me at the top of the stairs swinging these at him??
