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.

M390 - a martensitic high-performance chromium steel produced using powder metallurgy. Due to the alloy concept, it is characterized by extremely high wear resistance and high corrosion resistance. Thanks to its high wear resistance, it retains its edge shape, keeping the blade sharp for a very long time (requires minimal maintenance). Another advantage is its resistance to “wire” formation during sharpening. Steel with a high chromium content of 20.0% (Cr) and an admixture of 1.9% carbon (C), 4.0% vanadium (V), hardened to 59-61 HRC. This super steel is comparable to Carpenter's CPM 20CV or CTS-204P steels. Manufactured by Böhler Edelstahl in Kapfenberg, Austria.
Vacuum & Cryogenic - M390 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 converts retained austenite into martensite, significantly increasing hardness, wear resistance and overall durability. Thanks to these advanced processes, M390 steel ensures exceptional performance, offering both razor-sharp edge retention and extraordinary blade durability.
Blade - Sheepsfoot type, with a wide blade. Finished with a scratch-concealing Sandblasted method, a process in which fine sand particles are ejected under pressure onto the blade to give a stylish and practical look. The long cutting edge in relation to the Blade's length converges towards the needle-sharp tip of the knife. The thickness of the blade provides high strength while the high, flat grind gives excellent cutting edge geometry and extreme cutting performance. Ceramic ball bearings are responsible for the smooth and smooth operation of the knife's opening mechanism. The opening in the wedge allows both right and left-handed people to open the knife quickly and effortlessly. On the back of the upper jimping wedge, a notched thumb rest. A small choil makes sharpening easy. The whole is locked with the proven and popular liner lock.
Handle - is two pieces of Micarta composite (pressure-pressed canvas with synthetic resin), deeply textured to improve grip security, screwed to the steel frame of the knife. Chamfered cover edges eliminate sharp edges for comfort and improve grip confidence. The solid backspacer to which the grips are attached guarantees the rigidity and strength of the entire structure. The simple, solid construction gives the assurance of many years of use. A deep finger undercut (fore finger groove) improves grip confidence. The pivot is decorated with a stylized Kubey Knife brand logo. A two-position (right.left) titanium deep-carry clip allows you to carry the knife discreetly in your pocket in tip-up (blade tip up) position.
