Xin Cutlery XinCraft 8'' Chef Kitchen Knife Maple Burl, Acid Etched 440C (XC137)

XinCraft 8" Chef Maple Burl, Acid Etched holds a special place in the Xin Cutlery lineup as an example of an artisanal approach to the modern kitchen knife. The XinCraft line was created for users who expect not only high-quality materials, but also a conscious design in which form directly follows function. A chef's knife is a demanding, but at the same time extremely versatile tool. This model was handmade by experienced craftsmen, which translates into consistency of geometry, meticulous finish and high blade culture. Blade of san-mai construction is based on a core of 440C steel , sheathed in layers of 410 stainless steel, which provides very good edge stability, wear resistance and high cutting precision. The Chef profile is characterized by a clearly defined back line and a long, straight section of the cutting edge, which promotes smooth, controlled movements during slicing. The convex grind used gives the blade a gently convex geometry, increasing the efficiency of material penetration and reducing drag when working with products of varying textures. The Handle, made of resin-stabilized maple burl, is designed for long-lasting use and stable grip. Its contoured design supports the natural positioning of the hand, ensuring good balance of the entire knife and high blade control even during long cooking sessions. XinCraft XC137 is a tool aimed at conscious users who are looking for a knife with distinct character, high precision and durability, capable of coping with both everyday work and more demanding culinary tasks.

440C martensitic alloy stainless steel has a high 1.10% carbon (C) and high 16.0% chromium (Cr) content and impressive corrosion resistance. It is characterized by a hardness in the 57-59 HRC range. The high carbon content produces chromium carbide compounds, providing excellent wear resistance and edge retention after hardening. Due to its high hardness, the steel is suitable for the manufacture of cutting tools for knife and scissor blades and medical instruments.

Vacuum - 440C steel has undergone a specialized heat treatment process. Vacuum Heat Treatment - the steel is quenched in a vacuum environment, which minimizes oxidation and ensures more uniform metal properties. This process increases the strength and structural integrity of the steel.

San-mai is a special three-layer blade design, in which the hard core that forms the cutting edge is “wrapped” with two more flexible layers of steel. This combination makes it possible to achieve very good sharpness and its long retention, while at the same time making the blade more resistant to breakage and damage compared to a classic single-steel wedge. It is a solution derived from Japanese blacksmithing traditions, valued both for its functional properties and the characteristic transition drawing between the core and outer layers visible on the Blade.

Blade - with Chef profile is designed for maximum cutting control and versatility in the kitchen. The long, straight line of the cutting edge allows the blade to run smoothly while slicing, and the clearly marked tip allows for precise operations requiring accuracy. The convex grind used gives the edge a gently convex cross-section, which improves the ability to penetrate the material and promotes clean separation of slices without wedging. The multi-layered san-mai structure, finished using the acid-etched method, not only emphasizes the knife's craftsmanship, but also promotes blade stability and even stress distribution during operation. The overall design emphasizes smoothness of cutting, precision and predictable behavior of the blade with various cooking techniques.

Handle - made of resin-stabilized maple burl and brass spacers, combined in a design that ensures high durability and stability. Its shape was developed so that the hand naturally aligns with the axis of the blade, which improves control and reduces fatigue during prolonged work. The use of different materials allows for the right balance between the weight of the Handle and Blade, resulting in a neutral, predictable knife handling. Careful surface finish ensures a secure grip, regardless of the slicing technique or the type of products being processed.
