Japanese Round Carving Chisel YOSHIHIRO Uchimaru Nomi - 6 mm

Product detailed description

YOSHIHIRO – manufacturer of traditional Japanese tools and instruments used for precision craftsmanship. It produces both traditional and modernized carpentry tools.

Uchimaru Nomi 内丸鑿 - a "U"-shaped chisel used for carving round profiles 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 from soft steel, which absorbs impacts when struck with a wooden mallet or metal hammer, thereby reducing the chance of damaging the tool. However, the edge is made from extremely hard carbon steel, which achieves a hardness level of 62 HRC for classic Nomi chisels, up to 67 HRC for Japanese chisels with HSS blades, whereas classic European chisels only reach a hardness of about 58 to 60 HRC.

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