Japanese Carpentry Chisel SENKICHI DOUSHO - 24 mm

Product detailed description

The blades of traditional Japanese Nomi chisels (鑿) are made by laminating two layers of steel. The body itself is intentionally made from a softer material, which absorbs impacts when struck by a mallet and reduces the chance of tool damage. However, the edge is made from extremely hard carbon steel, resulting in a layer with a hardness of 62 Rc for classic Nomi chisels, up to a hardness of 67 Rc for Japanese chisels with HSS blades, while classic European chisels only reach 58 to 60 Rc.

Handmade Nomi chisels are created using the method of forge welding, which was used worldwide before the advent of cheap mass-produced steel. Unfortunately, this once-excellent technique is practically no longer used in chisel production outside of Japan today.

Features of the Nomi Chisel

✅ Traditional Japanese Nomi chisel
✅ For general carpentry use
✅ Handmade
✅ Blade hardness up to 62 Rc
✅ Selected edge profile = less friction
✅ Edge at an angle = greater working depth
✅ Handle made of red oak
✅ Made in Japan

The edge is set into the handle at a slight angle, which allows for a greater working depth. The selected edge profile reduces the area that the chisel touches the processed wood and decreases friction. At the same time, it makes the chisel easier to sharpen and after re-sharpening, the blade maintains a straight shape. Sharpening these chisels is recommended using wet Japanese sharpening stones, rewarding you with excellent sharpness and edge durability for a long time.

The ferrule of the Nomi chisel needs to be fitted before first use.
