sword for military arts training

摘要

PURPOSE: A sword for practicing fencing is provided to correct the pose with recognizing the speed and angle of the sword by hearing the sound generated in brandishing the sword and to supply interest in practicing to a practicing person. CONSTITUTION: The sword for practicing fencing includes a hitting portion(13), a resonance portion(14), inflow holes(15) and an outflow hole(16). The sword is made of metal materials. The resonance portion(14) is formed inside the sword. The inflow holes(15) are formed on the lower part of the hitting portion(13) in order that the air flows in the resonance portion(14). The outflow hole(16) is formed on the upper part of the hitting portion(13) in order that the air, which flowed in the resonance portion(14), flows out. The air, which moves in a moment, generates the sound by oscillating the resonance portion(14).
