Special feature:He was born in 1598 as a son of Yoshiie. Yoshiie was also a swordsmith of Hizen province.
Tadakuni was a pupil of Tadayoshi the First who consolidated the foundations of Hizen-to.
Tadakuni was designated Harima Daijo in 1634 at the age of 37. At the same time he started
to make sword for the domain of Ogi in Hizen province. He passed away in 1691, aged 94.
He was very good at gunome-midare hamon with deep nioi-kuchi and his sword was ranked
at Shinto-Josaku. This blade has tiny Kitae-Kizu around the Monouchi part.
But it is not serious.
From Aoi Art: Harima Daijo Fujiwara Tadakuni made the Hamon originally.
That Hamon remind of cumulonimubus of the summer sky.
In Ha, there are many Sunagashi and Kinsuji.
According to the book, Tadakuni is mentioned as Jyo Saku on the book.
In my opinion, he is ranked as JyoJyo Saku.
This blade is masterpiece of Tadakuni.
The blade has already the NBTHK Juyo paper.
We recommend this sword very much.
