Tsuba of oval form decorated with clematis six-petal flowers, tendrils, and leaves in cast brass with details carved in kebori, inlaid on iron plate carved in low relief (kebori and sukidashi-bori). Hitsu-ana plugged with shakudō. Copper sekigane.
Heianjō (or Ōnin) school. Unsigned. Mid Muromachi period (1454-1513). Dimensions: 87.2 x 84.3 x 4.3 mm. Tsuba is illustrated and described in Gary D. Murtha's "Onin-Heianjo-Yoshiro" book on pages 38-39. Mid-Muromachi is the age attribution by Gary. “A picture book of Japanese sword guards. Victoria & Albert Museum“, published in 1927 presents us with a somewhat similar tsuba: "Floral ornament. Iron, with brass incrustation". V&A attributes the tsuba to Ōnin style, 16th century.
