I agree, they are lighter then a wood pair, but what we are looking for here is to develope muscle memory and the coordination needed to manipulate them without hurting yourself. They are a good teaching tool. When you have the moves down, then you switch to the heavier wood ones in order to get used to the feel. Barring that, if you insist on using the wood pair, then start slow. Build your control slowly increasing speed and intensity over time. Be patient and get comfortable with them. I don't recommend using them in an actuall conflict until you have done this. Also, remember that you have to take responsability for any injuries you inflict on others while using them. So be judicial. Only if its absolutly necessary(ie they are coming at you with a weapon and you feel your life is in danger).
