Two courts, sixty years of war, and the most dramatic silhouettes in the sword’s history: broad blades, extended points, true ōdachi later cut down into the majestic katana collectors prize. The Sōshū manner was the style of the age.
This mumei tanto features a solid gold habaki and is attributed to Enju Kunisuke on the sayagaki and Chikushi Nobukuni by the NBTHK Hozon paper. Dating from the late Nanbokucho to Oei period, it has a mitsumune (three-ridge) hirazukuri form with blade carvings and no sori. The blade exhibits a straight gunome-midare hamon with ko-nie, sunagashi, ginsen, and kinsen, and an itame-mokume hada.
