Special feature: The Uda faction was based on Ko-Nyudo Kunimitsu at the
end of the Kamakura period, and sword makers such as Kunihusa,
Kunimune, and Kunitsugu played an active part in the Nanbokucyo
period.
It is a sword maker that prospered from the end of the Muromachi
period to the Edo period. Of these, works that do not fall in the
Manbokucyo period are called Ko-Uda. The same group was originally
from Yamato Udagun and many of them have a strong Yamato style,
but you can see the We find So-syu den style part.

From Aoi Art: This work is a Hirauchi style work with a wide Mihaba and
a short Nakago, which is a typical Nanbokucyo era taihai, and the
Mitumune style taihai adds its features. Because this work has a strong
so-syuden appearance, it was identified as Tametsugu in the past, but
at the NBTHK Museum, it passed Jyuyo To-ken as Kouda. As a whole, it
becomes O-hada or nagare gokoro, and chikei is mixed and it becomes
blackish and northern style, and it becomes jigane reminiscent of
Norishige style. It is a work that is also evaluated.
It is a masterpiece that I definitely recommend.
