Masamune

General

Name origin: "Masamune" is Japanese for "Holy Sword." A fable exists in which a swordsmith, Masamune, had to face off against another expert swordsmith. After completing their work, the two thrust their swords into a river. Passing leaves were cut in two by the opposition, while Masamune's sword actually made the leaves float away due to its spiritual power.
