Specila feature: Hizen koku Kawachi Daijo Fujiwara Masahiro was
a son of the Yoshinobu who was called Masanaga and at kanei 2nd November
he changed his name to Masahiro. He passes away at Kanbun 5th Feb, 5th age 59.
He made many swords for 2nd generation Tadahiro.
He made unusual Cumulonimbus cloud style hamon and well repotted from that period.
Even in modern times, many sword collectors collect his swords.
This blade is thick nioikuchi gunome midare hamon and looks first generational
of the Musashi daijyo Tadahiro. We undestand the high technique of his blade.
The sword is very healthy without Kizu and flow.

From Aoi Art: First generation Kawachi Daijyo Masahiro made active
oogunome midare hamon like Thundercloud. He helped to make
for firat and second generation Tadayoshi and Tadahiro as Daisaku (made sword for them)
The sword is now Jyosaku ranking on the Fujishiro book
but I think Masahiro looks Jyo-Jyo saku or the top ranking shinto blade.
We can remind on the blue sky, active summer Thundercloud
We recommend this Juyo token for you.
