This 210mm gyuto features san-mai construction with a kurouchi tsuchime surface finish and measures 3.5mm at the spine heel, tapering to 0.8mm at the tip with a total weight of 179g. The double-bevel profile suits general-purpose kitchen tasks including mincing, slicing vegetables, and cutting meat.\u003c\/p\u003e\u003cp\u003eAogami Super carbon steel core achieves 62-65 HRC hardness, providing edge retention and sharpness characteristic of high-carbon Japanese cutlery.

The blade is noted as thin behind the edge yet slightly brittle, requiring appropriate cutting technique. Master sharpener Takayuki Shibata finishes each blade within the Masakage collaborative brand, which showcases Echizen blacksmiths from Takefu Knife Village.\u003c\/p\u003e\u003cp\u003eThis knife pairs the blade with a heart-shaped desert ironwood handle and blonde horn ferrule.
