Blade Type

The Bunka knife, a versatile and traditional Japanese kitchen tool, features a distinctive, angular tip and a wide blade. It's designed for precision tasks like slicing, dicing, and chopping. Ideal for handling vegetables, meat, and fish, the Bunka is a multifunctional knife celebrated for its utility and unique aesthetic.

Steel Type

Japanese White Steel #2, a traditional high-carbon steel, is cherished for its purity and fine grain structure, enabling razor-sharp edges, at the cost of being reactive. It is one of the easiest steels to sharpen, but cannot be left wet for even short periods otherwise rust spots can occur. If you’re fastidious in your knife maintenance, this knife can steel can be extremely rewarding to use.

Recommended Maintenance

Store it in a dry environment using magnetic strips, knife rolls, or sayas. Avoid hitting hard or frozen objects and twisting the blade while cutting. These knives are not dishwasher safe. Clean with hot water and a soft cloth, and dry immediately after use to prevent rust spots on the high carbon steel. For more information please read the blog below.

The packaging has been custom designed in collaboration with French artist Phillipe Weisbecker, of which this packaging houses one of the finest blades we have ever seen. The Blue 1 Damascus is a special collaboration between Chefs Edge and HADO.

Knife Care

This knife is made from a high-carbon steel and as such, will require a little more care than a regular off-the-shelf knife. It must be dried shortly after use, as prolonged exposure to moisture can cause rust spots to appear. A very light coat of oil during storage also helps to prevent rust spots. A patina (colouration and seasoning of the steel) will occur with use.

Dan D.
Great knife

This knife was wicked sharp out of the box and has a great heft to it. If you like a thicker spine and some weight this is perfect for you. I will say that the blacksmith finish was somewhat coming off when it arrived, but besides that it was a great purchase and a pleasure to use.

Lovey knife v sharp ootb

I love the handle. Grind is lovely and fine. Very sharp out of the box. Tip is extremely delicate and unfortunately tip was scratched on arrival but doesn’t detract from a lovely knife.
