Many smiths across the centuries carried the name Sadatsugu; the maker of this tanto was the son of Kanetsune of Ichijō (\u003cem\u003eIchijō-jū Kanetsune\u003c\/em\u003e) and a pupil of the first-generation Yasutsugu — the celebrated Echizen master, originally named Shimosaka, who was granted the \"Yasu\" (康) character by the Tokugawa and worked in the Keichō era (early 1600s). Sadatsugu accordingly belongs to the prestigious Echizen Shimosaka (Yasutsugu) school. In February 2025 the NBTHK (Nihon Bijutsu Tōken Hozon Kyōkai) examined the blade, certified it as a genuine (\u003cem\u003eshōshin\u003c\/em\u003e) work of Sadatsugu, and issued a \u003cem\u003eHozon Tōken\u003c\/em\u003e certificate.\u003c\/p\u003e\n\u003ch3\u003eThe koshirae\u003c\/h3\u003e\n\u003cp\u003eThe tanto is mounted \u003cem\u003eaikuchi\u003c\/em\u003e-style in a beautiful \u003cem\u003eWakasa-nuri\u003c\/em\u003e (Wakasa-lacquer) \u003cem\u003esaya\u003c\/em\u003e — the celebrated marbled lacquer of old Wakasa province — in vivid vermilion over black, polished to reveal its swirling, tortoiseshell-like pattern.
