The jigane of the fine Ko Mihara works is quite similar to that of Aoe.
In the past, our friend from America brought a rusted katana.
At first look, it was a sword that could be attributed as Aoe.
If it is polished though, the “moisture” appeared in the ha.
The blade eventually received Jyuyo certificate attributed as Ko-Uda.
This work is chirimen hada style with faint utsuri work appearing.
The sword is very fine that it may be attributed as Aoe school.
The Shinogi-ji area is pressed with Migaki-Bo (burnishing needle) so the masa on the itame is barely seen.
The sword will look different depending on the level of polish.
