Ryuhyo means "drift ice" in Japanese, capturing the essence of shimmering sea ice sliding across Hokkaido’s northern waters. This knife reflects that inspiration with a refined, elegant design and high-performance construction.
The blade is made from premium SG2 (also known as R2) powdered stainless steel, known for its razor-sharp edge, long-lasting durability, and resistance to corrosion. It features a sanmai construction, with a hard SG2 core clad between softer stainless steel layers. The blade is hardened to approximately 62 to 64 HRC, making it ideal for precision slicing and professional-level performance. The mirror-polished finish showcases a Damascus-style pattern that glimmers like drifting ice, complemented by a laser-etched Hatsukokoro logo.
With a 218mm edge length and a total length of 361mm, the Ryuhyo Gyuto offers a versatile profile perfect for slicing vegetables, meats, and herbs. Its 48mm blade height and 2mm spine thickness at the base provide a comfortable balance between agility and control. Weighing only 146 grams (5.2 oz), the knife feels light and fast in the hand. The octagonal ebony handle adds ergonomic comfort and a rich, natural aesthetic.
Care Instructions: Hand washing is essential—use mild soap and warm water, and dry the blade immediately after cleaning. Do not soak, as moisture may cause spotting. Always use a wood or plastic cutting board and avoid glass, stone, or metal surfaces. For sharpening, we recommend high-quality whetstones in the 1,000 to 6,000 grit range. Store the knife in a sheath or knife block to protect the edge, and avoid chopping bones or frozen foods to preserve the fine cutting performance.
