Japanese Carpentry Chisel SENKICHI DOUSHO - 9 mm

Product detailed description

The blades of the traditional Japanese Nomi chisels (鑿) are made by laminating two layers of steel. The body itself is intentionally made of a softer material, which absorbs shocks when struck with a mallet and reduces the chance of tool damage. However, the edge is made of extremely hard carbon steel, which during the manufacturing process becomes 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.

Handcrafted 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 carpentry use
✅ Handcrafted
✅ Blade hardness up to 62 Rc
✅ Selected blade profile = less friction
✅ Blade at an angle = higher working depth
✅ Handle made of red oak
✅ Made in Japan

The blade is set into the handle at a slight angle, which allows for a higher working depth. The selected blade 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 retains its straight shape. Sharpening these chisels is recommended using wet Japanese whetstones, which will reward you with excellent sharpness and blade durability for a long time.

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