Ryuhyo means drift ice in Japanese, symbolizing the serene, glimmering sheets of sea ice that move across the northern waters of Hokkaido. The Ryuhyo 240mm Gyuto channels this imagery with a striking design and high-performance build crafted for serious cooks and professionals alike.
The blade is forged from premium SG2 (R2) powdered stainless steel, offering an exceptional blend of sharpness, edge retention, and corrosion resistance. It features a sanmai construction, where a hard SG2 core is layered between softer stainless cladding for added durability and easier maintenance. With a hardness rating of approximately 62 to 64 HRC, it is built for precision work and long-lasting sharpness. The mirror-polished blade boasts a Damascus-style pattern that mirrors drifting ice, finished with a laser-etched Hatsukokoro logo for subtle elegance.
With an edge length of 244 mm and an overall length of 390 mm, this gyuto offers added reach for larger prep tasks without sacrificing control. The blade height of 53 mm and a spine thickness of 2 mm at the base provide a confident and balanced feel. Weighing just 184 grams (6.5 ounces), it remains lightweight and agile in hand. The octagonal ebony handle is both ergonomic and beautifully understated, providing a warm contrast to the polished blade.
To care for the knife, hand wash only with mild soap and warm water, and dry it immediately after use. Avoid soaking, as excessive moisture may lead to spotting. Use only wooden or plastic cutting boards and steer clear of hard surfaces like glass, stone, or metal. Sharpen with quality whetstones in the 1,000 to 6,000 grit range for best results. Store the knife in a sheath or knife block and avoid cutting bones or frozen items to preserve the fine edge.
