37,46 €This product is intended for use only by adults with knowledge and experience in handling sharp cutting tools. Improper use of the knife can result in serious injuries. The blade is extremely sharp and can easily cut through skin and tissue; therefore, extra caution should always be exercised while cutting, and hands should be kept away from the cutting edge. To prevent the knife from slipping, it is recommended to cut on a stable, non-slip surface and avoid excessive force, which may cause uncontrolled blade movement.
Leaving the knife on the edge of a table, countertop, or in easily accessible places—especially where children are present—poses a significant safety risk. The knife should always be properly secured after use, ideally by placing it on a stable surface or storing it in designated knife blocks, protective sheaths, or magnetic strips. The knife should never be used for tasks it is not designed for, such as opening cans or prying objects, as this can damage the tool and lead to dangerous accidents.
A dull blade increases the risk of injury, as it requires more force and is more likely to slip from the material being cut. Therefore, it is essential to sharpen the knife regularly to maintain optimal sharpness. Additionally, proper cleaning and drying of the knife are necessary to prevent corrosion and bacterial growth. Periodic inspection of the handle and blade is recommended to check for cracks, chips, or looseness. If any damage is detected, the knife should be repaired or replaced immediately.
When using the knife, focus solely on the task at hand—avoid talking on the phone, watching television, or other distractions while cutting. Ensure proper lighting in the workspace for better visibility and control. Please note that some countries or regions have laws restricting the ownership and carrying of knives. Before purchasing or using this knife, verify that its use is legal in your location according to applicable regulations.
Following these safety guidelines will help ensure safe and effective knife use, minimizing the risk of accidents and extending the lifespan of the tool.

14C28N - martensitic chromium stainless steel is the latest achievement in the range of knife steels produced by the Swedish steelmaker Sandvik. Its optimized chemical composition, featuring a unique combination of elements, ensures the highest quality, excellent edge performance, high hardness, and corrosion resistance. By reducing the carbon content to 0.62% (C) and increasing the chromium content to 14.0% (Cr), as well as adding 0.11% nitrogen (N), corrosion resistance has been significantly improved. Considered an improved version of 13C26 steel. Unbeatable in the price/quality category!
Vacuum & Cryogenic - 14C28N steel undergoes a specialized heat treatment process comprising two key stages. During Vacuum Heat Treatment, the steel is hardened in a vacuum environment, which minimizes oxidation and ensures more uniform metal properties. This process increases the steel’s strength and structural integrity. Cryogenic Treatment: After heating, the steel is rapidly cooled to extremely low temperatures, often below -100°C (-148°F). This transformation converts residual austenite into martensite, significantly increasing hardness, wear resistance, and overall durability. Thanks to these advanced processes, 14C28N steel delivers exceptional performance, offering both razor-sharp edge retention and remarkable blade durability.
Blackwashed - a blade finishing method that combines two techniques. Black Coating - a protective, non-reflective black coating. Stonewashed - after the coating is applied, the blade undergoes a process that gives it a slightly aged, satin-matte appearance and effectively masks minor scratches and marks caused by use. The final result is a unique, aged look with a matte, dark finish that is both stylish and practical. It is a more aesthetic variant of the classic black stonewashed.
Blade - reverse tanto type, finished with the Blackwashed method, which masks scratches and prevents glare. The long cutting edge, with a pronounced bevel, tapers toward the needle-sharp tip of the wide blade. The blade thickness ensures high durability, while the high, flat grind guarantees excellent cutting performance. Ceramic ball bearings ensure smooth and seamless operation of the mechanism and assist in opening the blade using a quick index-finger flipper after opening the crossguard. On the spine of the blade, upper jimping provides a textured thumb rest. Liner-Lock mechanism.
Handle - G10 composite grips (glass fiber pressed under pressure with synthetic resin). Textured for improved grip, bolted to the steel knife frame. The so-called open-backed construction without a typical backspacer, held together by steel spacer sleeves, facilitates cleaning. The simple, solid construction ensures many years of reliable use. Two-position (right/left) steel deep carry clip allows for discreet carrying of the knife in a pocket in the tip-up position (blade tip pointing upward). Above the clip is a lanyard hole for threading a safety or decorative cord.
