Detailed information

Product detailed description


SENKICHI 千吉 – manufacturer of traditional Japanese tools and instruments used for precise craftsmanship. Produces both traditional and modernized carpentry tools.

Uchimaru Nomi 内丸鑿 – a "U"-shaped gouge used for carving round profiles and for other fine carving work. It is made 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, producing a layer with a hardness of 62 HRC for classic Nomi chisels, up to 67 HRC for Japanese chisels with HSS blades, whereas classic European chisels reach only a hardness of 58 to 60 HRC.

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