Features:Yusuishin Sadayoshi, born in 1908 (Meiji 41), was a prominent swordsmith from Shizuoka Prefecture.
His real name was Enomoto Sadayoshi.
He won multiple awards including four Encouragement and Effort Awards and was selected six times for exhibitions, eventually becoming a Mukansa swordsmith.
He was a disciple of Gassan Sadakatsu.
In 1943 (Showa 18), he moved to Mishima City in Shizuoka, where he forged blades using spring water from Mt. Fuji.
Though he ceased sword making for a time after the war, he resumed around 1951 (Showa 26), producing many award-winning works.
He was a versatile swordsmith, mastering styles such as Soshu-den, Bizen-den, Mino-den, and Yamato-den.
He also inherited the skill to produce Ayasugi-hada from his teacher Gassan Sadakatsu.
He ultimately achieved the status of Mukansa.
This piece is a collaborative work with his student, Sadao.
It remains healthy and retains plenty of the original Ha (cutting edge).
This blade is expected to receive even greater appreciation in the future.

A magnificent sword forged using spring water from Mt. Fuji, and it is in excellent polish.
Highly recommended for ownership.
