Dragonfly: Victory symbolism and Samurai high-ranking:
Dragon-fly shaped was made in Japan in the 17th century. Embellishments such as this were used by high-ranking lords so they could be easily located on the battlefield. Hilts of swords and arrow quivers were also commonly emblazoned with the image of the fearless, swift and courageous dragonfly. In Japan the dragonfly is known as the "victory insect", or kachimushi
