Japanese Skewed Carving Chisel YOSHIHIRO – 9 mm

Product detailed description

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

Kiwa Nomi キワ鑿 – an angled chisel used for shaping inner corners, dovetails, and hard-to-reach places. It is made in various radii and widths. A traditional motif in Japanese woodworking is the precise finishing of a board to fit tightly around a pillar or a natural element, such as a stone or a tree trunk. 

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 impacts when struck by a wooden mallet or metal hammer, thus reducing the chance of damaging the tool. However, the edge is made of extremely hard carbon steel, which during production reaches 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 splintering of the wooden end of the handle under the blows of the mallet.
