Description

Round (marugata) iron tsuba, unsigned, attributed by the NBTHK paper to the Ko-Tōshō school, the early swordsmith-style guard makers. The plate is thin, with a hammered surface (tsuchime-ji) and a rounded rim (maru-mimi). Decoration is limited to small negative openings (in-sukashi) forming the kukuri-zaru motif, the bound monkey of popular amulets: a tiny figure on one side and two rounded openings on the other, achieved with great economy. The photographs show both faces, the rim and close-ups of the surface: a dark, mottled and stable iron patina, with no active rust or visible cracks, and a small sekigane at the base of the central opening. According to the original seller it measures 8.26 × 8.04 cm, the rim is 0.25 cm thick, it weighs 90 g and comes in a paulownia box. The NBTHK Tokubetsu Hozon Tōsōgu paper, no. 2010669, dated 2 July 2024, describes it as a kukuri-zaru openwork tsuba, mumei, Ko-Tōshō.

Strong points

  • NBTHK Tokubetsu Hozon Tōsōgu paper (2024)
  • Attribution to the Ko-Tōshō school
  • Understated kukuri-zaru motif in negative openwork
  • Hammered iron with a dark, stable patina

Points to bear in mind

  • Unsigned: a school attribution, not an individual maker
  • Small sekigane in the central opening
  • The period is inferred from the attribution and style; the original seller dates it to Edo
