Nihei knives are produced in Fukushima, Japan. Forged from SLD tool steel with a soft stainless cladding rated at 64hrc. SLD is considered a semi stainless steel, though not as reactive as more pure high carbon steels, it will form a patina over extended use. SLD is known for its incredible edge retention and sharpens very easily. The blade is finished with a nashiji pattern on the top of the blade and a mirror polish towards the edge of the blade. These knives have thin grinds with light convexing and very nice distal taper. Octagonal chestnut handles with pakka wood ferrule.
