Features: \u201cSue Sa\u201d refers to the later generation of the Sa school, a group of swordsmiths active during the Nanbokuch\u014d period, believed to be disciples and related smiths of the famous Osafune Sa (\u014csa).
\nAmong them, signed works by smiths such as Yasuyoshi, Yukihiro, and Kunihiro exist, but are mostly limited to tant\u014d and wakizashi.
\nAs such, identifying specific smiths from this group is extremely difficult.
\nCommon traits include irregular boshi patterns and pointed turn-backs, both of which are seen in this piece.
\nPart of the hamon also features sharp, pointed returns, characteristic of this school.<\/p>\n
