Special feature : In the Muromachi period, Harima, Mimasaka and Bizen province
had been prospered under the protection of the Akamatsu family. Above all,
Bizen province has turned out a great many talented swordsmiths.
Supplying the demand of the Age of Provincial Wars in Japan, a large number of swords
were made there in the late Muromachi period. Sukesada has become a synonym
for the Osafune School though the founder was Mitsutada.
It is regrettable that a deluge devastated the School in Osafune districts in Tensho era.
Such is the way of the world that even the Osafune School, that prosperity
and power had been unparalleled, perished in this way in the deluge.
Old swords are all that is left to tell how once the swordsmiths lived.
This blade looks like Ichimonji style sword. There are a lot of works in Ha.
There is Oo-Hada (Umegane) on Sashi Ura side. But it is not serious.
The Naganaki Naoshi style nice sword.
