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)

TLDW #26 – Traditional Yaki-Ire, Hardening a Tanto

During the hardening process the clay layer causes a split second difference in cooling time which creates two different hardness areas in the same piece of steel. The edge cools faster and forms a very hard steel structure called martensite while the body cools slower and forms a very tough steel structure made of ferrite and pearlite. The boundary between these two areas is called hamon and is commonly seen as a frosted line down the length of a polished sword blade.

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

SOTW #20 – Assembling the Furusato Tanto

This discarded block of wood from the Congo/Zaire sat for several years waiting for the right blade to make the best use of it. This precious dark chocolate coloured hardwood is locally called Tshikalakala or Dikela, meaning turn around or circle back, and this particular piece has a slightly curving grain that follows the line of the saya. The name Furusato (故郷) means home place or hometown and contains the ideas of being rooted or grounded wherever one may sojourn, and a confidence and longing for return. more about this project

TLDW #24 – Making an Ireko (nesting) Saya

An ireko saya (入れ子鞘, nesting scabbard) is a lining inside the saya which protects the blade from the hardwood. Furusato (故郷) means home place or hometown and contains the ideas of being rooted or grounded wherever one may sojourn, and a confidence and longing for return. This tanto has a simple and elegant form with a natural and humble mounting that reflects the rustic satoyama lifestyle and suits the aesthetics of the way of tea. more about this project

Inome Tanto

The inome (pronounced “ee-no-may”, 猪の目, eye of the boar) name comes from the pierced heart-shape designs of the decorative o-seppa (washers) on either side of the tsuba (handguard). This lovely motif is ubiquitous in Japan, seen often in architecture, furniture, and sword… Continue reading →
