Description

Round (marugata) iron tsuba, unsigned, attributed by the NBTHK to the 金山 (Kanayama) school, one of the great workshops of pierced iron tsuba in Owari and Mino provinces. The openwork (ji-sukashi) draws a lozenge inscribed in the circle, crossed by parallel bands that build overlapping squares; the paper describes the motif as kasane-masu, overlapping measuring boxes. Two lobed hitsu-ana open on either side of the seppa-dai (ryō-hitsu-ana). The photographs show iron with a dark, stable patina, the granular surface typical of the school and a thin square rim (kaku-mimi koniku) where some tekkotsu appears. The central opening retains pale metal sekigane, somewhat irregular, and the seppa-dai shows recesses and marks from old fittings on both faces. No active red rust, cracks or knocks are visible. According to the original seller it measures 70 × 70 mm. It comes with NBTHK certificate 特別保存刀装具 (Tokubetsu Hozon Tōsōgu) no. 227791, dated 27 June 2006, which describes it as mumei, Kanayama.

Strong points

  • NBTHK Tokubetsu Hozon Tōsōgu paper (no. 227791, 2006) to the Kanayama school
  • Geometric design of overlapping squares (kasane-masu) in pierced iron
  • Dark, stable patina; granular rim with subtle tekkotsu
  • Photographed on both faces and along the rim

Points to bear in mind

  • Unsigned: a school attribution, not an individual maker
  • Somewhat irregular pale metal sekigane and marks of old fittings on the seppa-dai
  • The Momoyama dating is stated by the original seller; the paper does not give a period
  • The original seller titles the motif as overlapping pestles (kasane-kine); the paper describes it as kasane-masu
