Aoi Art’s Comment:Yūsui Shin Sadayoshi (湧水心貞吉) was born in Fukushima Prefecture in 1908.
He studied under Tsukiyama Sadakazu and Tsukiyama Sadaichi, winning numerous awards before achieving Mukansa status.
He was particularly skilled in forging Gassan-style hada, Bizen-den, and Soshu-den, producing exceptional works inspired by the Shizu and Koto traditions.
He passed away in 2000 at the age of 92.
This sword is modeled after a Masamune-style masterpiece.
The intricate hataraki within the hamon stands out exceptionally.
As it undergoes further polishing, its value is expected to increase significantly.
We strongly recommend preserving this sword as a treasured item in your collection.
With proper care of the nakago, this piece will continue to stand as a top-tier work.
