This gyuto 210 mm in Aogami #2 (Blue Steel #2) from Hatsukokoro handles the full range of everyday kitchen tasks: vegetables, meat, and fish. At 210 mm, the curved profile suits both rocking and push-cut techniques. The length stays manageable in smaller kitchens while providing enough blade surface to work larger pieces without repeated passes.
Aogami #2 (Blue Steel #2) is developed by Hitachi Metals from Shirogami #2, with chromium (0.2,0.5%) and tungsten (1,1.5%) added for stronger edge retention between sharpenings. The steel responds well to sharpening on water stones and takes a very acute edge. Like all carbon steels, it develops a progressive patina with use, a normal result of controlled oxidation. For those who value patina development, Shirogami #2 remains the more reactive option, which has its own appeal depending on preference. To facilitate maintenance, the Aogami #2 steel core is coated with two layers of stainless steel.
Care
Wipe the blade dry immediately after each use. Patina that develops over time is normal and expected. Apply a light coat of camellia oil for extended storage. Never wash in the dishwasher.
