The Hatsukokoro Irodori Aogami #2 Rainbow Damascus Gyuto 240mm is a Japanese chef's knife that is both technical and visually distinctive. It belongs to the Irodori series, recognizable by its multi-layered Damascus steel with contrasting hues, creating a pattern known as “Rainbow Damascus.” The 240 mm blade has a versatile gyuto profile, suitable for cutting meat, fish, and vegetables in both professional and domestic kitchens.
The core of the blade is made of Aogami #2 (Blue Paper Steel #2), a carbon steel renowned for its ability to achieve a high level of sharpness and for the quality of cut it provides. The construction is sanmai, with a carbon steel core wrapped in multiple decorative layers forming the colorful Damascus pattern. This structure combines cutting performance with striking aesthetics. Like all carbon steel, Aogami #2 will develop a patina over time and requires careful wiping after use.
The finish presents a sharp contrast between the polished cutting edge and the damask surface with its undulating patterns. The kanji engraved on the face of the blade reinforce its artisanal identity. The octagonal birch handle (stabilized wood type) offers a comfortable and balanced grip, complemented by a clear ferrule that creates a clear visual transition with the blade.
When in use, this 240 mm Japanese gyuto knife stands out for its precise and direct cutting feel, typical of high-performance carbon steels. The blade easily penetrates food with little resistance, particularly when making long, fluid cuts. Its length encourages broad, regular movements, ideal for slicing meat or chopping large volumes of vegetables. However, it requires a suitable cutting board and careful maintenance to preserve its edge and finish.
Immediate drying after washing is recommended. Avoid dishwashers and hard surfaces. Regular maintenance with a sharpening stone will maintain the high performance of Aogami #2.
