Process: Carving the Inside – Aikuchi Tanto Koshirae

In this video the tsuka is carved first, starting with the omote side and then the ura, carving each half from the mune to the ha. The saya is next, starting with the omote and then the ura, each half beginning with the fitting of the blade (from the mune towards the ha) and then the fitting of the habaki area (koiguchi). Finally the halves are glued together with rice paste glue, wrapped with leather cord, and wedged tightly to dry overnight. The first half is almost real time, the repeat steps edited out during the second half. The wood is hounoki, carve carefully and check often! carving the outside | making the fittings

Inside look at a traditional kaiken mounting

A look inside the carving of a small kaiken tanto mounting (futokoro-gatana) with additional examples from an Edo period tsuka and an even older shirasaya.

The omote is the “public side” of a tanto or sword, the side that faces outwards both when being worn and when on display. The edge faces upwards and the handle is on the left when displaying nihonto. The ura is the “private side” and faces away from the viewer when on display and towards the body when worn.
