New weapons in karate Posted on March 12, 2016 by Tessa The dojo finished up the Tonfa sessions and moved on to Nunchaku, or nunchucks! These look like the hardest weapons to learn! I was amazed no one smacked themselves in the head with these things! I think the kids like the coolness factor of sticking them in their belts. :-) That's Lex on the right.
