Hatsukokoro Kurogane Blue #2 Gyuto 210mm
The Hatsukokoro Kurogane Blue #2 series represents honest, blacksmith-made Japanese knives rooted in tradition and function. Handcrafted in Tosa, Japan, each knife is hammer forged by a working blacksmith, not factory finished or cosmetically refined. These are true tools, built for performance first.
At the core is Blue #2 carbon steel, heat treated to approximately 62 HRC, prized for its excellent edge retention, sharpness, and feedback on the stones. The blade is constructed in san mai, with the hard Blue #2 core wrapped in soft iron cladding that adds toughness and resilience while reinforcing traditional forging methods.
The blade is finished with a rustic kurouchi surface, intentionally left raw and textured. Because these knives are made by hand, it is normal—and expected—to see small scratches, forge marks, or minor dents in the finish. These details are not defects; they are part of what makes each knife authentic and unique, reflecting the human hands that shaped it rather than machine perfection.
Ground with an even 50/50 double bevel, the Kurogane series is comfortable for both right- and left-handed users and performs well across a wide range of kitchen tasks. The grind emphasizes clean cutting and solid food release, making it a dependable daily-use gyuto for cooks who value function and character.
Please note that this knife features carbon steel and iron cladding, which will react to moisture. Wipe the blade dry during and after use to prevent rust and allow a natural patina to develop over time.
Finish sharpening is recommended to tailor the edge to your preferred cutting style and maximize performance.
Care Instructions: Hand wash only. Dry immediately after use. Avoid bones, frozen foods, and twisting cuts. Use wooden or rubber cutting boards. Store safely in a saya or blade guard when not in use.
