Features:In the late Muromachi period, Japan entered the Sengoku (Warring States) era. Due to high demand, swordsmiths began producing blades in workshop-style mass production. This piece shows beautiful jigane with a slightly dark tone, suggesting it may be from an earlier period, likely around the Eisho era (1504–1521).
