$2,900.00 $3,000.00

We are pleased to announce the arrival of a breathtakingly beautiful tanto accompanied by a Hozon certificate of authenticity.

The blade has been beautifully polished throughout and is a sound piece with virtually no flaws. It features an unokubi construction with mizuki grooves carved on both sides of the blade. There is a minor scratch approximately 3 mm long on the ha, about 8 cm from the tip on the sashira side. The jigane features a well-refined itame hada, and the notare hamon displays a moist, niokuchi. Although this tanto is unsigned, Sato Kanzan, an authority on Japanese sword appraisal, has authenticated it as a work by Sanjo Yoshinori and has issued a sayagaki. Furthermore, in August 2024, the Society for the Preservation of Japanese Art Swords also certified this tanto as an authentic work by Yoshinori and issued a preservation certificate recognizing it as a piece of high value worthy of preservation for future generations.

Sanjo Yoshino is the name of a renowned swordsmith who was active primarily during the Muromachi period in Yamashiro Province (present-day Kyoto Prefecture), as well as the name of the school he founded. Alongside Heianjo Nagayoshi, he is known as one of the leading smiths representing Yamashiro-style swords of the Muromachi period. Naga-yoshi is said to be the master of Muramasa. While tradition traces Naga-yoshi’s lineage back to the Kamakura period, almost no signed works from that era survive; the earliest confirmed extant works date from the early Muromachi period (around the Oei era).

This Unokubi style dagger is sure to satisfy your desire for ownership and is a magnificent piece that beautifully exemplifies the characteristics of the Koto period.
