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 stainless chromium steel is the latest development in the range of knife steels produced by the Swedish steelworks Sandvik. The optimized chemical composition with a unique combination 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 nitrogen to 0.11% (N), the corrosion resistance has been significantly increased. Considered an improved version of 13C26. Unbeatable in the price/quality category!
Vacuum & Cryogenic - 14C28N steel undergoes a specialized heat treatment process involving two key stages. Vacuum Heat Treatment - the steel is hardened in a vacuum environment, which minimizes oxidation and ensures more uniform metal properties. This process increases the strength and structural integrity of the steel. Cryogenic Treatment After heating, the steel is rapidly cooled to extremely low temperatures, often below -100°C (-148°F). This transformation changes the residual austenite into martensite, significantly increasing the hardness, wear resistance and overall durability. Thanks to these advanced processes, 14C28N steel ensures exceptional performance, offering both razor-sharp edge retention and extraordinary blade durability.
Blade - classic drop point, stonewashed finish to mask minor scratches caused during use. The thickness of the blade in combination with the flat grind gives excellent cutting edge geometry and extreme cutting performance. Ceramic ball bearings ensure a smooth and quiet mechanism and support the opening of the blade with the help of a hole in the handle or flipper, which, when opened, acts as a mini guard to prevent the hand from sliding onto the blade. Upper jimping, a corrugated thumb rest, on the spine of the blade. The locking mechanism is a durable Liner Lock.
Handle - profiled grips made of titanium 6AL4V, micro-milled with a fine texture. The whole is screwed to a solid backspacer, also made of titanium. The simple, solid construction ensures many years of use. The pivot axis is adorned with a titanium cap (Pivot Cap) in a contrasting color. Two-position (right/left) titanium deep carry clip allows you to carry the knife discreetly in your pocket in a tip-up position (with the tip of the blade up). The forefinger groove improves grip and creates a mini guard to prevent the hand from slipping onto the blade.
