Yoshinari (吉作) was a sword smith who worked in Tosa province around the Kyohô era (1716).  He was the son of Kôzuke no Kami Yoshikuni (上野守吉国) and the nephew of Mutsu no Kami Yoshiyuki (陸奥守吉行).  His father’s home province was Ôshû and he is called Magobei.  Both Yoshikuni and Yoshiyuki went to Osaka and entered the Yamato no Kami Yoshimichi Mon (大和かみ吉道) and studied with the first generation Yoshimichi.  He later moved to Tosa Province in Shikoku and continued to forge swords in the style of his teacher.

Yoshinari followed in the style of his father and uncle and the blades of all three smiths are very similar and, of course, show many of the traits of the Osaka Shinto style of their teacher, Yoshimichi.  Their blades are shinogi zukuri, shallow sori with a medium and sometimes slightly extended kissaki.  The hada is a tight ko-itame and there will be ji-nie.  The hamon will be a mixture of chôji and gunome with ashi, nioi fukai (thick nioi) with ko-nie, and a long yakidashi.  Their nakago will be fairly long with a saki (end) that is iriyamagata and the yasurimei will be ô-sujikai.

This katana is the masterpiece of the works of Yoshinari.  It encompasses the typical traits of the works of his father and uncle, equaling or surpassing them.  The nagasa (length of the cutting edge) of this blade is 71.2 cm or 28.03 inches.  The sori (curvature of the blade) is 1.6 cm or 0.62 inches.  The width at the hamachi (base of the blade) is 3.26 cm or 1.28 inches, and the width at the Kissaki (point) is 2.21 cm or 0.87 inches.  The thickness of the blade (kasane) is 0.7 cm or 0.27 inches.

This blade dates to the early part of the Edo period around Kyohô era (early 1700’s).  The shape of the kissaki (point if the blade) is slightly stretched giving it an especially majestic overall shape.  The hada (grain of the metal) is ko-itame with jinie creating an especially beautiful jigane.  The hamon (temper line) starts at the hamachi in suguha as one would expect and then explodes into a beautiful chôji-midare with many ashi as well as sunagashi and kinsuji throughout.  The bôshi is round and notare in style.

This katana has an ubu (un-shortened) nakago with only the one original mekugi ana.  The habaki is a double habaki made of copper that has been wrapped in heavy gold foil.

Accompanying this blade is a very attractive koshirae comprised of a black roiro lacquered saya and a tsuba and fuchi/kashira made of shakudo nanako with gold colored dragons.  The menuki are also gold colored dragons.  A very tasteful koshirae that was the pride of the last Samurai to own this blade.

The blade is in excellent polish with no flaws or defects and is housed in a shirasaya.  The mounts have a wooden blade so that they may be exhibited and enjoyed.  This blade was awarded NBTHK Hozon papers in  the first year of Reiwa (2019) that attest to its excellent quality and condition and its authenticity.
