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 reduces reactivity on carbon steel knives, reduces the cost of production, and gives the knife a very characterful, rustic aesthetic prized by many knife enthusiasts. Kurouchi finishes vary widely in appearance, uniformity, and durability. Rarely will pictures do these finishes justice as they have a very complex look and feel to them.
