Nimai(Two Piece) is the Japan's traditional approach to the kitchen knife making, this construction method is typically found on knives with native Japanese origins like Yanagiba, Deba and Usuba. When constructing a Nimai knife, a piece of soft cladding metal will be placed onto a core steel, the two pieces of metal are then forgewelded and shaped into the knife.

The Nimai knives are usually sharpened in single-bevel fashion, with hardened core steel exposed on the flat/hollow-ground side and soft cladding warping over the other side and over the spin. The soft cladding offers support for the harder yet more brittle core steel so the knive can have a thin, sharp edge while have some overall strength. Since the single bevel Japanese knives usually don't have a secondary bevel, the combination of soft cladding and hollow-grind have made the sharpening process easier than Monosteel and Honyaki knives.

Knifemaker in Japan have been encoporating newer features into their products, including the more traditional Nimai knives, damascus pattern and stainless steel were two of them. With the core steel completly exposed on the hollow-ground side, the stainless cladding cannot protect the core from rusting like it does on Sanmai constrction, this lead to the combination of stainless core steel and stainless cladding. With addition of damascus pattern, the Nimai knives with traditional design have never been this attractive and approachable.

Mirror Polish is a simplistic yet hightly demanding process, where the roughness of the metal surface is gradually removed with higher and higher grit abrasives, leading to a extremly smooth surface with only specular reflection, just like a mirror.

The Mirror Polish can be applied to various constructions, ranging from Damascus to Honyaki. It can reveal the beautiful Hamon on the Honyaki blade, and form textural contrast on damascus. The perfect surface is highly appreciated, but it also means a lot of care must be give to avoid it being scratched.

The stabilized birch burl handle adorning the Hatsukokoro chef knife is a testament to both exquisite craftsmanship and natural beauty. Birch burl, prized for its intricate grain patterns and unique textures, undergoes a meticulous stabilization process to enhance its durability and stability, ensuring longevity and resilience against moisture and wear.

The handle's ergonomic design offers a comfortable and secure grip, allowing for extended periods of use without fatigue. Its smooth contours and balanced weight distribution contribute to precise control and effortless maneuverability during culinary tasks.

The natural variations in color and grain of the birch burl create a visually captivating aesthetic, making each handle distinctively unique. This harmonious blend of functionality and aesthetics not only elevates the chef knife's performance but also adds a touch of elegance to the kitchen, reflecting the unparalleled craftsmanship of Hatsukokoro knives.
