A Shodai Masahiro Katana (肥前国河内大掾藤原正広)

Kawachi Masahiro was born Sadenjiro in 1607 and died at only 59 in 1665. The son of Yoshinobu — who was himself the adopted son of the great first generation Shodai Tadayoshi — he began his career signing as Masanaga and even cut signatures on behalf of the ailing Shodai Tadayoshi (dai-mei). Recognising his exceptional talent, Lord Nabeshima Katsushige suggested the young smith take the name Masahiro, and so Shodai Masahiro was born. Ranked Jo-saku and rated Wazamono for cutting ability, he stands among the finest smiths the Hizen tradition ever produced.

This long and splendid katana is a tour de force. The steel is forged in the classic Hizen manner: a tight ko-mokume that refines into the school’s celebrated konuka-hada, so densely worked it resembles fine rice bran under magnification. Masahiro was renowned for his thick nie-deki, and this blade delivers in full — generous splashes of sparkling nie crystals animate the hamon from base to point, with lively kinsuji and generous sunagashi threading through the activity. The boshi is a spectacular kaen, the thick clusters of nie at the tip blazing like fire.

The sword comes complete with a superb Edo period uchigatana koshirae. The saya is finished in black raden fuemaki lacquer — symmetrical mother-of-pearl flute stripes — dated and certified to the middle Edo period, circa 1688-1780. The tsuba is a polished iron example with gold cloth inlay attributed to the prestigious Umetada school, bearing the sangaibishi triple-diamond kamon of the Ogasawara daimyo who ruled the Karatsu domain in Hizen from 1817 to 1871. The fuchi-kashira is decorated with large crawling dragonflies in shakudo — the dragonfly being the quintessential samurai symbol of forward-only determination — certified by the NTHK-NPO to the Iga school of the late Edo period. The tsuka is wrapped in a bold two-strand tsunegumi-kumiagemaki weave in gold silk over stingray skin, with large shakudo dragon menuki. An ibushigin flower niju-habaki in oxidised silver completes the mounting. Every component is a statement piece — together, they form one of the most complete and visually compelling Edo period mountings one could wish for.
