The blade is made of 32 layers of softer stainless steel on the outside and has a core of VG10 steel. Kurouchi is not a type of knife but rather a traditional, rustic finish. Kurouchi roughly translates as blacksmith’s finish. Kurouchi knives retain the scaly residue left from the forging process. The finish lowers the cost of production, and gives the knife a very characterful, rustic look prized by many knife enthusiasts. The handle is made of walnut with a bolster of mahogany. The Kanji (Rooij) on the blade gives the knife its own identity.
