Of all the many pupils of the great Sagami-province smith Masamune (see also lot 4), Sadamune is generally believed to have most faithful to the master's style; according to one tradition he was Masamune's son. Although few if any authentic signed works of Sadamune are known, his style was comparatively uniform and unvarying, so that this blade can be confidently assigned to him on grounds of the hamon [tempering pattern] with its combination of the gently undulating notare with the more sharply articulated gunome and the wood-grain forging pattern with jinie and chikei. His blades are gentler in appearance than those of his great master, with much quieter deployment of the shiny particles of crystalline steel known as nie.
