The Harukaze AS Petty 135mm is a compact, high-performance knife designed specifically for Chef Knives To Go as part of this excellent price-conscious lineup. These knives offer outstanding value by pairing thoughtful construction with one of Japan’s most respected carbon steels, Aogami Super. The result is a serious cutting tool that punches well above its price point.
Aogami Super (AS) is derived from Aogami #2 (Blue #2) and enhanced with additional carbon, chromium, and tungsten. This formulation is widely regarded as the finest of the Hitachi Blue paper steels, offering exceptional edge retention while remaining responsive and precise on the stones. The core steel is hardened to approximately 63 HRC and clad in soft stainless steel, providing added toughness and helping reduce reactivity to moisture and acidic foods.
At 135mm, this petty is nimble and precise—ideal for in-hand work, trimming proteins, slicing fruit, prepping herbs, and detailed tasks where control matters most. The blade is stiff and confidence-inspiring, making clean cuts with minimal effort. It’s finished with a comfortable oval rosewood handle paired with a durable black pakka wood ferrule, giving the knife a classic look and balanced feel in hand.
Care Instructions: Although the blade is stainless clad, the exposed Aogami Super edge is a high-carbon steel and can develop patina or surface rust if left wet. Hand wash only, dry thoroughly after use, and avoid the dishwasher. Do not leave the knife soaking in water or resting wet on the board. Store the knife dry, and apply a light coat of food-safe oil to the edge if the knife will be stored for extended periods.Brand: Harukaze
