TLDW #27 – Forging a Saya Nomi (鞘鑿)

Saya-nomi (鞘鑿) are a type of Japanese chisel with several unique features designed for carving the inside of a wooden scabbard or handle. Hand forged from a reclaimed harrow tooth, the elongated neck is slightly curved for clearance and the bottom and side corners are slightly rounded and the tip is slightly bull-nosed to facilitate cutting inside a concave surface without leaving corner marks. A scrap of magnolia makes a clean, simple handle for use as a push chisel. more about the process of carving saya (scabbards)

First Lighting of the Forge & Antique Habaki Utsushi (写)

First lighting of the newly rebuilt charcoal forge in the island kajiba followed by stamping the tang and then hand forging and filing a classical tanto style habaki, silver soldered in the charcoal forge and closely based on an antique Edo period habaki. An utsushi (写) is a closely based study of another work for the purposes of professional development. Polishing and patinating will be done after the saya has been carved. information about the machigane | habaki making process

Installing the Higuchi (tuyere)

Installing/repairing the higuchi (tuyere), the point where the air enters the forge and temperatures are very high. In this case the fire clay to form the tuyere and fit it to the brick construction Japanese swordsmith forge is a traditional brasque recipe consisting of 6:2 charcoal powder/fines to natural clay, mixed with just enough water to stick together well. The forge must be allowed to dry fully before lighting or steam will crack the clay. see more of the island forge kajiba project
