This Jigane looks like Rai school.

Boshi is small round shape.
Special feature : This blade has the gold inlay signature “Ryokai”.
From our personal point of view, this blade is Ryokai or Rai school.
But the NBTHK judged as Chikuchi Ryokai.
Hisanobu who has descended the skill of Ryokai has moved to Chikushi and produced swords.
Alike Hisanobu work, it has soft feeling Jigane well grained with fine forging done.
Hisanobu and Yoshizane were some of the sword smiths in the group
that has descended the Suguha Deki and well grained Ryokai and Yamashiro.
This blade is quite healthy. And the shape is very rare.
We strongly recommend this Tanto.
There are slightly rusts. We will remove it when you purchase.
