Description

An unsigned marugata tsuba which the NBTHK Tokubetsu Hozon Tōsōgu paper attributes to the Ko-Kinkō school and titles 四方扇透鐔 (shihō ōgi sukashi tsuba), 'openwork tsuba with fans in four directions'. A shakudō plate of deep black patina is framed by a twisted-rope rim, nawame dote-mimi, carved in relief. Within it, a silver ring finely engraved with waves and swirls encloses a crown of pierced spokes, gilt spokes alternating with open slits, crossed by four diagonal bars; the two side openings have cloud-shaped outlines. Two Japanese publications reproduced in the photographs (the book 文化の中の刀装具 (Bunka no naka no tōsōgu), plate 3, and the September 2000 issue of the newspaper 刀剣春秋 (Tōken Shunjū)) read the design as a water wheel among waves, place it in Kyoto in the Momoyama period and attribute it to Ko-Shōami; the paper keeps to Ko-Kinkō. The photographs show both faces and the rim: original patina, gilding intact, only minor handling marks on the seppa-dai. According to the original seller it measures 7.74 × 7.70 cm, 0.57 cm thick, and weighs 150 g; it comes with a round maki-e lacquer box decorated with bamboo and a stream.

Strong points

  • NBTHK Tokubetsu Hozon Tōsōgu paper (2013), attributed to the Ko-Kinkō school
  • Published in the book Bunka no naka no tōsōgu and in Tōken Shunjū (2000)
  • Fine shakudō with a carved silver ring and gilt iroe spokes
  • Precisely carved twisted-rope rim (nawame dote-mimi)
  • Round maki-e lacquer box

Points to bear in mind

  • Unsigned: the paper gives a school attribution, not a maker
  • The literature attributes it to Ko-Shōami; the NBTHK paper does not adopt that attribution
  • Minor handling marks on the seppa-dai, slightly irregular edges to the central ana and a stable greenish tone inside the piercings
