"VG10" is a high-quality knife steel that achieves a sharp edge and high durability. The added cobalt enhances the strength of the hardened metal base, firmly retaining carbides. This allows for improved cutting durability. Furthermore, by reinforcing the base, the material rigidity is also enhanced, reducing the deflection of the blade tip while sharpening, enabling a sharper edge. [Features] - Reduces deflection of the blade tip, allowing for a sharper edge - Strengthened base due to cobalt addition - Significantly improved durability and edge retention - Enhanced material rigidity by reinforcing the base *For more details, please refer to the PDF document or feel free to contact us.

"VG5" is a stainless steel knife material that is well-balanced in hardness, wear resistance, and corrosion resistance, making it popular for general kitchen tools. By increasing the amounts of carbon (C) and molybdenum (Mo), and adding vanadium (V), it enhances the refinement of carbides and strengthens the metal structure. The ratio of chromium (Cr) and carbon (C) components has been pursued more deeply than that of regular stainless knife steel. It has become an all-rounder steel type suitable for a wide range of applications. 【Features】 ■ Well-balanced component design ■ Equipped with the necessary hardness, wear resistance, and corrosion resistance for knives ■ Supported for general kitchen tools ■ Enhances carbide refinement and metal structure *For more details, please refer to the PDF document or feel free to contact us.

"VG2" is a stainless steel recommended for thin-bladed knives and machine blades that require not only ease of handling but also sharpness. By controlling the carbon (C) content, corrosion resistance is ensured. The addition of molybdenum (Mo) also increases the toughness of the steel. Furthermore, to maximize hardness and utilize corrosion resistance, a well-balanced composition ratio is established to form a uniform structure of fine carbides. 【Features】 ■ Equipped with necessary hardness and wear resistance for cutting tools ■ Designed with consideration for ease of sharpening and edge retention ■ Control of carbon content and addition of molybdenum ■ Balanced cutting tool performance through careful assessment of composition ratios *For more details, please refer to the PDF document or feel free to contact us.

"VG1" is a stainless knife steel that has a dense and tough structure, good forgeability, and is easy to heat treat while exhibiting excellent corrosion resistance. Containing 1.0% carbon (C), it has hard primary and secondary carbides coexisting in the base material, contributing to its wear resistance. Additionally, with 14% chromium (Cr), it effectively enhances corrosion resistance and strength. You can experience a cutting performance akin to that of high-carbon steel despite being stainless. [Features] - Simple component design - Dense and tough structure - Good forgeability - Easy heat treatment - Resistant to wear and excellent edge retention *For more details, please refer to the PDF document or feel free to contact us.

"SPG2 (Super Gold 2)" is a high-end stainless high-speed steel that combines the characteristics of high-speed steel and corrosion resistance. It is produced using powder metallurgy, resulting in a uniform and fine microstructure without segregation compared to conventional melting methods, which leads to excellent forgeability and machinability. Additionally, it allows for the inclusion of a large amount of high-alloy components. Please feel free to contact us when you need assistance. 【Features】 ■ High hardness ■ High toughness ■ Good wear resistance ■ Excellent corrosion resistance *For more details, please refer to the PDF document or feel free to contact us.

"CoSP (Cobalt Special)" is a product that achieves component uniformity and fine dispersion of carbides through a special dissolution method. It contains 1.1% carbon (C) and 16% chromium (Cr), with the addition of tungsten (W) contributing to improved tempering resistance, while molybdenum (Mo) further enhances corrosion resistance. Additionally, vanadium (V) refines the structure, and cobalt (Co) strengthens the base material, further enhancing the longevity of the cutting edge. [Features] - Excellent corrosion resistance, wear resistance, grindability, and workability - Ultra-high-grade stainless knife steel - Improved tempering resistance - Exceptional sharpness and edge retention achieved through a special dissolution method *For more details, please refer to the PDF document or feel free to contact us.

"Clad Art" is a product that utilizes the "design quality" obtained through dissimilar metal bonding, made from multilayer clad metal. We are engaged in creating products that leverage clad materials in items such as fountain pens, golf putters, paperweights, seals, and building materials, and we have received positive feedback for gifts and commemorative items. Our products are also used in decorative items for places such as the Echizen City Library and the Fukui Prefectural Industrial Promotion Facility (Sundome Fukui), contributing to the promotion of Echizen forged blades as a regional specialty. [Features (Titanium Clad Putter)] - The multilayer effect synergistically enhances rebound and shock absorption, resulting in ideal ball roll and a soft, pleasant feel. - The plastic forging effect from roll forming improves the elastic strength of the material, expanding the sweet spot and helping to prevent mis-hits. - The design structure features a three-dimensional expression of the milled surface on the face and the striped pattern of the base metal. *For more details, please refer to the PDF document or feel free to contact us.

"Clad metal" refers to a metal that is coated entirely or partially with another metal, and the interface between them is metallurgically bonded. Unlike those joined by plating or adhesives, it undergoes a process of composite formation. As a result, it possesses "composite characteristics" that allow for the acquisition of properties not previously attainable, or the complementary coverage of weaknesses in opposing properties. [Features] - Does not break or bend (toughness) - Easy to process - Improved corrosion resistance at the cutting edge - Enhanced sharpness and long-lasting sharpness (in the case of cutting tools) - Resource-saving *For more details, please refer to the PDF document or feel free to contact us.
