Signature (Mei): 長州住藤原清重 Chōshū jū Fujiwara Kiyoshige - zaimei (signed) Swordsmith: Fujiwara Kiyoshige (Hasegawa Hachizaemon line, Chōshū / Nagato Province) School / Tradition: Chōshū school, descended from the Nioh (二王) lineage Period / Province: Edo Period (Shintō, early Edo per NBTHK) / Nagato Province Certificate: NBTHK Hozon Kanteishō No. 3036993 (Reiwa 7 / 2025) Mounting: Black lacquer koshirae with karakusa iron tsuba and gold-highlighted fittings Blade Length (Nagasa): 68.4 cm (2 shaku 2 sun 6 bu jaku) Curvature (Sori): approx. 1.5 cm - to be confirmed Mekugi-ana: 3 Shape: Shinogi-zukuri with iori-mune and chū-kissaki Jihada: Bright, tightly forged itame Hamon: Suguha-chō with gentle notare, soft nioiguchi with ko-nie Boshi: Ko-maru This Katana is a signed (zaimei) work by Chōshū jū Fujiwara Kiyoshige , a swordsmith of Nagato Province (Chōshū, today's Yamaguchi Prefecture), certified by the NBTHK in a current Hozon appraisal (Reiwa 7 / 2025) and classified as a Shintō work of the early Edo period.
