| An unsigned sword attributed to Iyo-no-jō Munetsugu. Iyo-no-jō Munetsugu was a swordsmith of the Saga domain in Hizen Province in the early Edo period, ranked as a jō-saku smith. He received the title Iyo-no-jō in Keichō 11 (1606).Unlike the Hizen blades of the Tadayoshi line, his workmanship does not show the typical konuka-hada. Instead, the jihada is ko-mokume mixed with itame, well covered with ji-nie, with chikei appearing. The hamon is generally gunome mixed with small notare, with strong nie, showing a Sōshū-den style, with prominent kinsuji and sunagashi within the temper.This blade shows strong nie and well-executed Sōshū-style workmanship, with a Keichō-shintō style sugata. The attribution to Iyo-no-jō Munetsugu is therefore convincing. From the condition of the nakago, it is likely that this blade was originally regarded as a fine sword that later became mumei.Passed NBTHK Hozon Tōken shinsa in 2025. |
