The Ryuho range developed by Yuzo Hamono is part of a demanding approach to Japanese cutlery, combining top-quality materials with precise manufacturing. These knives have been designed to offer an excellent level of performance over time, while retaining the meticulous aesthetics typical of Japanese damascened blades.
Each model in the range is designed to guarantee a clean, fluid and even cut, with a comfortable grip. Whether you're a seasoned amateur or an experienced user, Ryuho knives enable you to work efficiently with a wide variety of foods, with precision and consistency.

A core of SG2 steel renowned for its performance
Ryuho knives are built around a core of Japanese SG2 steel, a powdered stainless steel renowned for its fine structure and high performance. This type of steel achieves a hardness of around 62 to 63 HRC, offering excellent edge retention. The cutting edge performs better for longer, limiting the frequency of sharpening while maintaining consistent cutting quality.
Thanks to its stainless composition, SG2 steel is also highly resistant to corrosion, making it easy to maintain on a daily basis. It is the right choice for users wishing to access top-of-the-range steel without the constraints of more sensitive carbon steel.
Robust, aesthetic damascus construction
The SG2 core is surrounded by several layers of steel forming a damascene structure. This construction enhances the overall strength of the blade, while providing a certain flexibility in the face of mechanical stress. Damascus also plays a role in cutting comfort by slightly limiting food adherence when cutting.
The wavy patterns visible on the blade are the result of this layering process. Each knife has a unique finish, which reinforces its character and high-end appearance.
Fine blade geometry for controlled cutting
The knives in the Ryuho range are characterized by a fine blade geometry that favors clean penetration of food. The fineness of the blade reduces the effort required for cutting, while improving precision. The blade profile, particularly on multi-purpose models, makes it easy to alternate between different types of cut.
The combination of SG2 steel's hardness and the fineness of the grind gives a fluid cutting feel, particularly appreciated for precision work such as mincing or cutting fish.
A complete range of profiles for every application
The Ryuho range is also distinguished by the diversity of blade shapes on offer, to meet different kitchen needs. You'll find versatile models like the gyuto, Japan's equivalent of the chef's knife, ideal for working with vegetables as well as cuts of meat. The more compact santoku is particularly appreciated for quick, everyday cuts, especially for slicing and dicing with precision.
More specific profiles are also available, such as the kiritsuke gyuto, recognizable by its fine, angular tip that offers great precision on delicate cuts. This diversity enables each user to choose a knife suited to his or her cooking style, while maintaining aesthetic and technical consistency within the range.
A balance designed for ease of use
Ryuho knives are designed to offer a good balance between blade and handle, which improves control during use. The handle provides a stable, natural grip for prolonged use. Careful assembly ensures a smooth transition between the different parts of the knife, without discomfort during handling.
This ergonomic approach reduces fatigue, even during prolonged cutting sessions, while maintaining constant precision of gesture.
An ideal range for upmarket Japanese knives
Yuzo Hamono's Ryuho range represents an excellent gateway to top-of-the-range Japanese knives. It offers the benefits of high-performance powdered steel, solid damascus construction and balanced design, without compromising on ease of use.
Thanks to the variety of models available and their consistent build quality, these knives are equally suited to demanding domestic use and more intensive use. They offer a precise, stable and durable cutting experience, designed to accompany the user over the long term.
