Kanshou and Bakuya: Gān Jiàng and Mò Yé (干将かんしょう・莫邪ばくや, Kanshō - Bakuya?) are “married” twin swords representing Yin and Yang, crafted by the blacksmith Gān Jiàng (干将, Kanshō?) of Wu during the Spring and Autumn PeriodWP of China. They were crafted more for the sake of crafting, as if questioning the meaning of the swordsmith, than for any real idea behind their creation. They were created without vanity, and lack a sense of purpose found in other swords. They contain no fighting spirit to defeat others nor a competitive spirit to beat other weapons, and they contain neither the desire to be famous nor the faith to accomplish great deeds.
