Edo was the sword’s age of connoisseurship: the Hon’ami appraisers, the shogunal register of famous blades of 1719, and a thriving literature turned the sword into an object of study even as it ceased to be drawn in war.
This katana is signed by Yasuyuki of the Naminohira school in Satsuma province, dated Kyowa 3 (1803) when he was 61 years old. It features a robust form with a wide mihaba, thick kasane, and bo-hi carvings. The blade has a well-forged itame hada with jikei and a bright, moist appearance, reminiscent of Hizen's konuka hada. It is accompanied by an NBTHK Tokubetsu Hozon certificate.
