Nunchaku (er jie gùn) is made of 2 short (usually wooden) sticks linked by a piece of rope. It became very popular after Bruce Lee introduced it in his movies. Nunchaku offers a shorter range distance for striking than the long staff but its flexibility (via the rope) makes it a very useful and powerful weapon. Practicing Nunchaku sharpens the skills of Chinese martial arts fighters. It allows working on reflexes, blocks, combat distance, dodging and all the skills necessary for a good fighter.
