Japanese Carving Chisel YOSHIHIRO Tataki Sotomaru - 15 mm

Product detailed description

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

Sotomaru Nomi 外丸鑿 – a type of chisel used for shaping inner curves. It is made in various radii and widths. A traditional theme in Japanese woodworking is the precise processing of a board so that it fits tightly around a column or a natural element, such as a stone or a tree trunk. Another use is for embedding lock cases and door hinges. This chisel is perfectly suited 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 from soft steel, which absorbs the impact when struck with a wooden mallet or a metal hammer, thus reducing the chance of tool damage. However, the edge is made from extremely hard carbon steel, producing a layer with a hardness of 62 HRC for classic Nomi chisels, up to 67 HRC for Japanese chisels with HSS blades, while classic European chisels only reach a hardness of 58 to 60 HRC.

The steel crown, a metal ring at the end of the handle of Japanese chisels, needs to be precisely fitted before first use to prevent the wooden end of the handle from splintering under the strikes of the mallet.
