An interesting project to craft a knife for an existing sheath. The like-new sheath was part of an estate sale and was custom crafted by former military Rock Leatherworks in Quebec, Canada. With some careful planning and accurate forging it can once again serve a useful purpose.
The tang is constructed in a similar manner to a Japanese sword requiring only a single bamboo peg to hold the knife assembly together. In addition to the sense of beautiful simplicity, this design allows the knife to be taken apart for cleaning, polishing, detailed cutting tasks, or major resharpening work.
The core of this project is a charcoal-forged blade, water quenched with clay and sharpened with waterstones, a western style knife that has the foundation of the Japanese sword. The steel for the blade came from the steel pile of another knifemaker decades ago (and appears to be T440C), the Teak wood for the handle came from a boat restoration, and the fittings are forged from a large electrical washer and reclaimed copper pipe. The removable peg is carved from susudake, a piece of bamboo that served for a century or more as part of the ceiling or roof in a kominka, darkened and hardened by decades of smoke wafting up from the irori hearth.
The blade is about 8″ long with a generous 5.25″ handle, an overall length of just under 14″, and around 15″ when sheathed. The spine at the munemachi is 6mm thick.

This blade was forged and yaki-ire performed at the museum forge. It began as an unknown piece of steel from another knifemaker almost two decades ago.
**Please note that in order to preserve the patina and texture of the reclaimed components involved in this mounting there may be minor damage, scuffs, variations in colour, and other indications of their stories over the centuries. Also the hamon is not likely where it appears by surface oxidization as this is 440c steel.
