  • Iron tsuba of round form decorated with eight roundels – circular emblems of flowers and/or family crests (mon) made of cast brass, pierced and chiselled in kebori, and with flat brass inlay (hira-zōgan) of vines or leaves all over the plate. Both hitsu-ana are trimmed with brass. Nakago-ana of trapezoidal form. A distinctive character of this tsuba is a mon at 12 hours, depicting paulownia, or Kiri-mon [桐紋] – a symbol of the Toyotomi clan, led by Toyotomi Hideyoshi (豊臣 秀吉, 1537 – 1598). Kiri-mon was also used as fuku-mon (alternative family crests) for the Imperial Family and Imperial Court. Another important emblem at 6 o’clock is the Katakura clan [片倉氏, Katakura-shi] family crest. Katakura Kagetsuna (片倉 景綱, 1557 – 1615), a retainer of Date Masamune (伊達 政宗, 1567 – 1636); Kagetsuna was operational in Hideyoshi’s Odawara campaign in 1590, which ultimately ended the unification of Japan. Unsigned but may be attributed to Koike Yoshirō Naomasa or his workshop (Yoshirō, orKaga-Yoshirō school). Dimensions: Diameter: 85.5 mm; Thickness at seppa-dai: 5.0 mm.
