Aoi Art’s Comment:This sword is the exact piece that won the Effort Prize at the 6th New Masterpiece Sword Exhibition.
Following this achievement, Yūsuishi Sadayoshi honed his skills further and became a mukansa (top-ranked) swordsmith.
His relentless dedication and the spirit of perseverance are evident in this work, making it a truly remarkable piece.
Even after being recognized as a mukansa swordsmith, achieving such a level of craftsmanship is no easy feat.
With a blade length of nearly 80 cm, this is an outstanding sword that has now been certified as Tokubetsu Hozon Token.
