Specification Brand : MASAMOTO BulletPoint1 : PROFESSIONAL JAPANESE SANTOKU KNIFE: This Japanese Santoku knife is an all-purpose kitchen tool ideal for slicing meat, vegetables, and fish. Its double-bevel edge makes it easy to use for both home cooks and professionals. Alongside the Gyuto, it's one of the most commonly used knives in Japanese kitchens. Handcrafted by MASAMOTO SOHONTEN, a trusted maker since 1866, this knife blends timeless tradition with modern performance to bring out the best in your cooking. BulletPoint2 : RAZOR-SHARP BLUE STEEL #2 BLADE: The blade is forged from premium Japanese carbon steel (Aogami Blue Steel No.2), known for its razor-sharp edge, excellent toughness, and long-lasting sharpness. It strikes a perfect balance of hardness and durability, providing a smooth and satisfying cut every time. Note: As a carbon steel knife, it is more prone to rust than stainless steel and requires proper care after each use. BulletPoint3 : KUROUCHI FINISH: This knife features a traditional Kuro-Uchi (black-forged) finish, where the darkened surface from the heat-treatment process is left intact. Not only does it give the blade a rugged, rustic appearance, but it also helps to resist rust slightly better. It’s a classic element of Japanese craftsmanship, offering both function and aesthetic character. BulletPoint4 : JAPANESE WA HANDLE: The lightweight wooden handle is crafted in the traditional Japanese Wa style, with a comfortable D-shaped design that fits naturally in your hand. The ferrule is made from durable water buffalo horn, adding strength and elegance to the overall design. This handle ensures a secure grip and precise control during use.

The KA Series Kurouchi Wa Santoku is completely hand-sharpened by highly skilled and experienced craftsmen, resulting in exceptional sharpness and a refined level of finish.Masamoto KA Series knives use a blade core made of Hitachi Blue Steel No.2 (HRC 62–63), which is forge-welded and sandwiched between layers of soft iron. Blue No.2 steel is produced by adding Chromium (0.2–0.5%) and Tungsten/Wolfram (1.0–1.5%) to a base of White Steel No.2. This composition offers comparable sharpness to White Steel No.2 but provides greater strength, toughness, and edge retention—ideal for users who need a consistently sharp edge throughout the day. However, it may take slightly longer to sharpen than a White Steel No.2 blade.Each KA Series knife is fitted with a traditional Japanese magnolia wood handle and a water buffalo horn ferrule.
