Made by master Craftsman Itsuo Doi these knives are designed to harness the power of the Guren flame, the hottest flame use to forge. Doi hammers each blade to perfection with a stunning unique hammered kurouchi finish.

This range is made from Blue Steel No.2, which is a carbon steel with HRC rating of between 63 and 65. This very hard steel has incredible sharpness and exceptional retention while also being easy to sharpen.

These knives are thick and sturdy making them exceptional workhorses, strong but yet incredibly sharp, like really impressively sharp due to their hand sharpened expert techniques and fantastic materials. 

Kurouchi roughly translates at 'blacksmith's finish', and retains some of the residue of the forging process. This allows the knives to be cheaper, as some of the production process is removed, and also provides protection to the blade reducing the risk of corrosion. Not only that, but it is a stunning finish, and is very desirable right now.
