According to the authentification paper, the theme of this Menuki is squirrels (栗鼠) and chestnuts (栗). In Japan, squirrels have traditionally symbolized vitality, while chestnuts represent prosperity and the continuation of the family line. By incorporating these motifs into the Menuki of a Katana, the spirit of the samurai and a wish for the flourishing of future generations are expressed. Also, we estimate this Menuki is made from the Shakudou (赤銅), it is an alloy of copper and gold. This material has often been used for making sword mountings due to its properties. And the Shakudou gives the works elegant black color. While some colorings have partly faded due to aging, it seems that the gold overglaze painting, called the Kin Iro-e (金色絵), was initially applied to this Menuki. It makes an elegant color contrast with copper’s black color. Also, it adds decorativeness to this work.
