Japanese Carpentry Chisel SENKICHI DOUSHO - 42 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 shocks when struck with a mallet and reduces the chance of damaging the tool. However, the edge is made from extremely hard carbon steel, which during production becomes a layer with a hardness of 62 Rc for classic Nomi chisels, up to a hardness of 67 Rc for Japanese chisels with an HSS blade, whereas classic European chisels only reach a hardness of 58 to 60 Rc.

Handmade Nomi chisels are created using the blacksmith welding method, 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 woodworking use
✅ Handmade
✅ Blade hardness up to 62 Rc
✅ Selected edge profile = less friction
✅ Edge at an angle = higher 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 higher working depth. The selected edge profile reduces the area that the chisel touches the processed wood and decreases material friction. At the same time, this makes the chisel easier to sharpen, and after re-sharpening, the blade maintains a straight shape. Sharpening these chisels is recommended using wet Japanese whetstones, which rewards you with excellent sharpness and edge durability for a long time.

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