Ryuhyo translates to "Flowing Ice," a name that reflects this knife's smooth, gliding cut and the clean, fluid movement of its Damascus pattern. The Ryuhyo Petty 150mm is designed for precision work--trimming proteins, slicing fruit, and handling detailed prep with speed and control--making it an ideal utility knife for everyday kitchen use.
At the core is SG2 powdered stainless steel, a high-performance steel known for its extremely fine grain, high hardness, and excellent edge retention. Proper heat treatment allows SG2 to take a very sharp edge while maintaining good stability, and it sharpens cleanly on water stones. The thin, controlled grind gives the knife an effortless cutting feel, but like all hard Japanese steels, it should be used with care--avoid twisting cuts or hard foods to prevent chipping. A flowing Damascus cladding adds toughness and visual depth without sacrificing performance.
The octagonal ebony handle provides a secure, balanced grip and a refined traditional feel that complements the blade's clean lines and elegant finish.
Care Instructions: Hand wash only and dry immediately after use. Do not use a dishwasher or abrasive cleaners. Avoid cutting frozen foods, bones, or very hard items. Store dry in a blade guard, saya, block, or on a magnetic strip. Maintain the edge with a ceramic rod or strop between sharpenings and use water stones when full sharpening is required.Maker: Hatsukokoro
