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.
