The Hatsukokoro Aokitae Blue 2 Kurouchi Santoku 165mm with Black Chacate handle is a double-bevel general-purpose knife best fit for home cooks seeking a compact carbon steel blade for slicing, dicing, and mincing. Produced in Hyogo by Hatsukokoro, this santoku features Hitachi Blue 2 (Aogami #2) carbon steel with a kurouchi surface finish and san-mai soft iron cladding. The reactive carbon steel construction requires immediate drying after use to prevent oxidation, as the blade is not stainless clad.

Blue 2 steel measures 61-63 HRC and contains tungsten and chromium additions that improve toughness and edge retention while maintaining ease of sharpening. This 165mm profile has a less aggressive tip and offers controllable chopping action suited to everyday kitchen tasks. The octagonal Black Chacate handle pairs with a blade measuring 3.3mm at the heel, tapering to 1.4mm at the tip, with a total weight of 154g and 46mm heel height. The san-mai soft iron clad construction supports the high-carbon core, providing structural support for the cutting edge during preparation work.

Please don't wash knife with dishwasher, it will damage the wood handle;
Be careful not to leave the knife close to a heat source for a long time;
It is a lot more dangerous to cut with a blunt knife than a sharp knife!

Steel: Blue 2 / Aogami #2
Blue Steel No.2, also recognized as Aogami No.2, is a distinguished high carbon steel produced by Hitachi Metals Ltd, enhanced by the addition of chromium and tungsten to the base of White Steel No.2. This modification brings about an improvement in toughness and the creation of hard carbide molecules, which significantly boost edge retention. Although its sharpness is comparable to that of White Steel No.2, Blue Steel No.2 offers a slight advantage in maintaining its edge.

Widely favored for its versatility, Aogami No.2 is celebrated for its ease of sharpening and robust resistance to chipping, making it an ideal choice for those new to Aogami steel knives. Containing 1.0–1.2% carbon and achieving a typical hardness of 62–63 HRC on the Rockwell scale, it stands as the benchmark in evaluating Aogami steel cutlery.
