I just got some new weapons for kobudo - tonfa! Like most traditional Okinawan kobudo weapons, these were originally used for a more utilitarian purpose. In this particular case, the tonfa were originally designed as handles for turning a grinding wheel.
I'm now learning the kata "Matayoshi No Tonfa Ichi". I must admit, when I first started using the tonfa they felt incredibly awkward - probably the most awkward thing I've tried to do in karate so far. Someone even pointed out in the first class I started using the tonfa that I was sticking out my tongue while practicing - it took that much concentration for me. Thankfully, after a couple weeks it now feels a lot more comfortable. I'm pretty sure I'm no longer unconsciously sticking out my tongue. :-)
