Japanese Grooving Carving Chisel YOSHIHIRO Sankaku - 6 mm

Product detailed description

YOSHIHIRO – manufacturer of traditional Japanese tools and instruments used for precise craftsmanship. It produces both traditional and modernized carpentry tools. Sankaku Nomi 三角鑿 is a triangular "V" groove chisel used for grooving and other fine carving work. It is available in various radii and widths.

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 shocks when hit with a wooden mallet or a metal hammer, thus reducing the chance of damaging the tool. However, the edge is made of extremely hard carbon steel, which in production becomes 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 splintering of the wooden end of the handle under the blows of the mallet.
