Japanese Carving Chisel YOSHIHIRO Tataki Sotomaru - 9 mm

Product detailed description

YOSHIHIRO – manufacturer of traditional Japanese tools and instruments used for precise craftsmanship. Produces both traditional and modernized carpentry tools.

Sotomaru Nomi 外丸鑿 – the shape of a chisel used for shaping internal curves. It is made in various radii and widths. A traditional motif in Japanese woodworking is the precise processing of a board to fit tightly around a column or a natural element, such as a rock or tree trunk. Another use is for embedding lock cases and door hinges. This chisel fits perfectly for this purpose. 

The blades of traditional Japanese chisels Nomi 鑿 – are made by joining two layers of steel. The body of the chisel is intentionally made of soft steel, which absorbs the impact when struck by a wooden mallet or a metal hammer, thereby reducing the chance of damaging the tool. However, the edge is created from extremely hard carbon steel, which during production becomes a layer with a hardness of 62 HRC for classic Nomi chisels, up to a hardness of 67 HRC for Japanese chisels with HSS blades, while classic European chisels only reach a hardness of 58 to 60 HRC.

The steel ferrule, a metal ring at the end of the handle of Japanese chisels, needs to be precisely fitted before first use, to prevent splitting of the wooden end of the handle under the blows of the mallet.
