Special feature : At Muromachi period, Sukesada and Kiyomitsu were working at Bizen province.
Especially at the end of Muromachi, Sukesada introduce mass productive way to make swords
which is called Kazuuchimono. These swords were made by much shingane inside of the blade and covered by good jigane.
So it is easy to appear shingane steal after polish again.

But this kind of swords applied for the demanding Japanese swords not only Samurai but also exporting to China.
Even if Bisyu Osafune Sukesada, the blade was made around Eisyo era,
The Jigane is fantastic like Bizen Tadamitsu.
I have seen Jyuyo Token Bisyu Osafune Sukesada which was made Eisyo era.
It is true that Bisyu Osafune Sukesada(kazuuchi mono) downgraded assessment of Bizen school sukesada or Kiyomitu .
This sword is not mass productive item because the signature is Bizen Kuni Osafune Sukesada not Bisyu signature.
the blade is wide and thick with deep sori Ubu style sword.
We recommend this sword for you.
