Traditional Japanese Carpentry Chisel SENKICHI KIN - 12 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 of a softer material, which absorbs shocks when struck with a mallet and reduces the chance of tool damage. 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, 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 woodworking use
✅ Handmade
✅ Blade hardness 63 Rc
✅ Double hollow ground profile = less friction
✅ Blade angled = 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 reaching a higher working depth. A selected blade profile reduces the area the chisel contacts the processed wood, decreasing friction. At the same time, this makes the chisel easier to sharpen, and after re-sharpening, the blade retains a straight shape. Sharpening these chisels is recommended using wet Japanese whetstones, rewarding you with excellent sharpness and durability of the edge for a long time.

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