Yoshitora Kore wo konomu 由虎好之

Features: Taikei Naotane is renowned as one of the leading swordsmiths of the late Edo period. He was a student of Suishinshi Masahide and served as an official swordsmith to the Akimoto family of the Yamagata Domain.
He was active for approximately 50 years, from the Kyowa era through the Ansei era.
Naotane practiced the theory of reviving classical sword-making methods advocated by Masahide and was particularly skilled in the Soshu and Bizen traditions, producing numerous masterpieces. This work features a tightly forged masame (straight-grain) hada reminiscent of Go Yoshihiro. Exceptionally well executed, it demonstrates Naotane’s remarkable versatility and mastery of a wide range of techniques.
The name “Yoshitora” appearing in the inscription is thought to refer to Ino Ichiun, a spearman active during the late Edo period.
