Description

Katana by Jirōtarō Naokatsu (Shōji Jirōtarō), pupil and later adopted son of Taikei Naotane, smith to the Akimoto family of the Tatebayashi domain. A large shinshintō blade in shinogi-zukuri with iori-mune, nagasa 80.3 cm and sori 2.1 cm; according to the original seller, a rare, powerful piece whose workmanship stands beside Naotane's own. Ko-itame hada mixed with mokume, thick ji-nie, chikei and a faint utsuri; hamon of notare with gunome, chōji and togari-leaning elements, with a soft nioi-guchi, abundant ashi and yō, kinsuji and sunagashi. The tang is ubu with a single mekugi-ana, signed 次郎太郎直勝 on one side and dated 天保壬寅年十月日 on the other; the photographs confirm both signature and date. Designated Jūyō Tōken by the NBTHK at the 68th session; the certificate, the oshigata and the explanatory text are photographed. Supplied with a shirasaya and an uchigatana-koshirae with black roiro-lacquered saya, same-covered tsuka with brown ito, openwork iron tsuba and horn kashira, which the seller describes but does not date.
