This katana by Kozuke Daijo Minamoto Yoshimasa, a smith of the Seki Zendai School active in early Edo period Musashi, features a finely forged itame-hada and a magnificent gunome-midare hamon with abundant sunagashi and kinsuji. The blade is in excellent condition and comes with a high-quality koshirae featuring a polished full samegawa saya, as well as a shirasaya. Despite being greatly shortened (ō-suriage), it retains excellent balance and is suitable for both appreciation and iaidō practice.
