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 | final work

Making a Swordsmith Anvil from Scrap

A Japanese swordsmith style anvil made from junkyard scrap. The two side pieces are cast steel or iron John Deere 8255C rear counterweights from a shovel dozer. They weigh about 200-240lbs each and measure about 2 1/8″ x 14 3/4″ x 25″. There is a ‘T’ shaped face and stem that extends to the ground between the plates made from welded spring or tool steel and weighs about 70lbs.

The face is about 1 3/8″ x 6″ x 15 1/4″ and has a pritchel hole in it and a sharp edge for cutting on one corner. The combined weight of the plates bolted onto the face and stem should be between 475 and 520lbs. The finished anvil should sit 7-7.5 sun from the ground or from the seat height.
