This mumei katana is attributed by the NBTHK to Sue-Seki, a school from Mino Province active in the late Muromachi period. It features a deep, purposeful 2.3 cm sori over a 63.6 cm blade, characteristic of a 16th-century battlefield katana. The blade is mounted in a tasteful black Edo-period koshirae with an iron tsuba and gold shishi menuki.
