Iron tsuba of round form with design of double crossbar and two family crests (hikiryo-ni-kamon) in openwork (sukashi). Squared rim. Copper sekigane. Owari school. Early Edo period: Late 17th century (Kanbun / Enppo era). Height: 80.9 mm. Width: 80.8 mm. Rim thickness: 5.0 mm. Center thickness: 4.6 mm. Provenance: Sasano Masayuki Collection, № 172: "A paulownia and a clover are diagonally opposite two crossbars. This expressive design suggests a Higo origin, but the iron and the finish are certainly of the Owari school. Work of this nature may have been influenced by Hayashi Matashichi (1613-1699)."
