The fuchi and koiguchi are from a reclaimed buffalo horn souvenir, the kurikata is from a reclaimed horn button, the wrapping is rawhide samegawa, the mekugi is copper and silver. All of the parts are first shaped and fit, then the samegawa is wet formed to the handle contours, dried, and then attached with sokui (rice paste glue). After the scabbard and handle are lacquered, the horn parts will be polished and attached with sokui as well. The mekugi cap is soldered on with hard silver solder in the charcoal forge. carving the inside | carving the outside | final work
In this video the tsuka is carved first, starting with the fuchi end and then the kashira area, carving the profile outlines and then removing the material in between before carving the final shape and sculpting the details. The saya is next, first dimensioning the blank is to approximate size and then profiling the koiguchi and then the kojiri, removing the material and carving as close as possible to the final shape using kanna and kiridashi. Finally any remaining high points in the curves are smoothed with a fine rasp. carving the inside | making the fittings | final work
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
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. See the whole forge building process here.
The wider profile of the mountain style kotanto is inspired by a kamakura sword and has a more deeply curved tip (fukura-tsuku) and shorter drop point. The simple and humble mounting style is inspired by the age-old style of farming and foresting tools traditionally used in managing satoyama… Continue reading
The tools are simple and few, but the work is long and hard. A collection of clips documenting the steps and sounds involved at many stages of the process of crafting charcoal forged classical tanto and mountings from reclaimed materials. Footage from several recent projects is included, some extended and some previously unreleased, some from Japan and some from Canada, photos of the finished aikuchi tanto appears at the end of the video.
