Bladesmithing at the Museum Forge

Forging a custom forest kotanto in the swordsmith forge. The starting material was a harrow tooth, the finished blade is hirazukuri, mitsu mune, 140mm / 5.5″ nagasa, with a sturdy 6.5mm motokasane. The finish will be tsuchime (hammer texture) so there was no filing or polishing before yaki-ire, which was done at my forge for the dim and consistent light conditions.

Process: Making the Fittings – Aikuchi Tanto Koshirae

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
