A Classic Early Tachi
Kamakura period (early 13th century)
This slender ubu tachi in shirasaya has the deep koshi-zori curve becoming shallow in the upper part of the blade indicative of the very earliest curved swords, although the blade has a severe forging fault, is tired over larger areas, the hamon severely depleted, and the boshi lost, it must have once been a fine blade, portions of the hada which remain are of ko-itame with fine jinie, in places close to the chirimen-hada of early Aoe school work, the hamon has large cloudy koshiba leading to ko-midareba with complex activity
length 78.5cm.
