Previous answer is
Oo suriage Mumei Ho-Syo.
大擦上無銘 保昌
Special feature:Hosyo tends to think that Masame hada is usually a strong work, but this
means that Masame hada is often found in Sinto’s products.
In the original Hosyo, masame hada stands out well, but I think there are many works
that include other itame hada and Mokume hada.
This sword is a work that can be called the original Hosyo. Jigane has a long black chikei
on top of the ground iron and has a complex work with movement.
There is a soft rounded Hakikake, Hamon and Kinsuji.
