[ Highlight ]Oku Izumi-no-kami Tadashige was a Satsuma swordsmith of the mid-Edo period. He was the son of Oku Tadakiyo, and his first signature was ‘Tadashige Naminohira, Taniyama ju’. In his later years, he changed his signature to Hideoki. He died in Kyoho 5 at the age of 63. He was a student of Tsuda Sukehiro. This work is a good-looking piece with a slightly wider body width, an ordinary thickness and curvature, and a medium cutting edge. Itame-hada is well grained, with a flowing, itame grain texture, and the base is thickly nie with fine ground chikei sceneries, making it an outstanding jigane. The wavy blade pattern has a kin-sen and sunagashi with a flow in the alternating pattern, and the nioi is bright and nie is well done. Masakiyo and Yasuyo, also from Satsuma, forged swords at the Shibahama Palace and were allowed by the shogunate to use the hollyhock crest on their signatures. Tadashige was the senior of Masakiyo and Yasushiro, who are considered to be the twin great swords of Satsuma shinto, and is thought to have influenced the swords created by them.
