<Menuki & Wachigai>
This is a very unusual item called “Menuki” made at the end of the Edo period.
Menuki is a decorative fitting attached to the handle of a sword.
This shape is called “Wachigai”, a pattern with two or more rings hanging together, that has been used since the Heian period.
The shape formed by the overlapping of the two rings means that two people help each other and live together.
The shape has something to be connected with Mokumeganeya wedding bands, “Tsunagaru-Katachi”.
