21,16 €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.
RK-31574 Tactical Black Aluminum, Black Titanium is a tool designed for users who need a full-size knife for operational, field and survival tasks. Blade made of 7Cr17MoV stainless steel has been coated with Black Titanium, which increases abrasion resistance, reduces light reflections and enhances the blade's protective qualities in humid or contaminated environments. The blade's spear point geometry and full flat grind allow for effective cuts and punctures, essential for field operations. The full tang design guarantees integrity and durability even under heavy loads. The anodized aluminum Handle combines rigidity with low weight and ergonomics, providing a secure grip with both gloves and bare hands. A black nylon sheath is included for safe carrying and quick access. The 31574 will prove to be a reliable tool for rescuers, officers and outdoor enthusiasts who expect full readiness in all conditions.
7Cr17MoV is a martensitic chromium steel, often referred to as an improved version of 440A steel. Its nominal chemical composition includes about 0.60-0.75% carbon (C) and 16.0-18.0% chromium (Cr), with additions of molybdenum (Mo) and vanadium (V) in smaller amounts. The higher chromium content provides very good corrosion resistance in typical environments. Carbon is responsible for hardness, which after appropriate heat treatment can reach about 56-58 HRC, which is sufficient for many applications. Molybdenum increases hardenability and improves resistance to pitting corrosion, while vanadium contributes to the formation of fine carbides, which increases abrasion resistance and allows the cutting edge to remain sharp longer. 7Cr17MoV steel is widely used in the mass production of kitchen knives, folding knives for everyday use (EDC), multi-tools and outdoor equipment, where a good combination of corrosion resistance, acceptable hardness and ease of sharpening is crucial .
Blade - made of 7Cr17MoV stainless steel provides good sharpness retention and corrosion resistance. Black Titanium coating protects the Blade from abrasion and minimizes glare, which is especially important in operational activities. The spear point profile promotes precise cuts and piercings, while the flat grind improves efficiency in a wide range of applications. The blade's geometry is designed for versatility - from camp work to defensive operations, offering a balance between power and precision.
Handle - made of black anodized aluminum provides strength while keeping weight low. Its contoured form and surface texture promote grip stability in harsh conditions such as rain, mud or sweat. A rope hole in the back allows you to attach the knife to equipment or use a safety line. Included is a sheath made of nylon, allowing for safe and comfortable carrying on a belt or tactical equipment. The overall design offers the user ruggedness, modern aesthetics and full operational readiness.
