Description

Unsigned (mumei) tsuba attributed by its NBTHK Tokubetsu Hozon Tosogu paper to the Ko-Kinkō school (古金工, Ko-Kinkō), the soft-metal craftsmen active before the Edo period. It is of six-lobed mokkō shape (六ツ木瓜形, mutsu-mokkō-gata) and made of yamagane, a dark, unrefined copper, on a nanako ground. Both faces carry oak branches with leaves and acorns (橡栗図, probable reading: shōritsu-zu) in sukidashibori (鋤出彫), a relief obtained by cutting back the ground, scattered with gold dew-drops in zōgan; the paper mentions gold and silver dew-drops with iroe. The rim is sukinokoshi-mimi (鋤残耳), left standing as the ground was cut away. The photographs show both faces and the edge: an old dark patina, the gold drops almost all in place, wear to the nanako and to the high points of the relief with some lighter patches, and a few green spots on the edge. A metal fitting strip (sekigane) is visible along one side of the central opening. The original seller places it in the Azuchi-Momoyama period and gives 8.62 × 8.22 cm, 0.36 cm thick and 160 g; it comes in a paulownia wood box. Tokubetsu Hozon Tosogu paper no. 2004381, dated December 2017.

Strong points

  • NBTHK Tokubetsu Hozon Tosogu paper, attributed to the Ko-Kinkō school

Points to bear in mind

  • Unsigned: a school attribution, not a maker attribution
  • Visible wear to the nanako and the high points of the relief, with lighter patches
  • A few green copper-oxide spots on the edge and a sekigane strip in the central opening
  • The period is stated by the original seller; the paper does not give it
