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-19652 Rubbered Black / Coyote Aluminum, Titanium is a modern combination of rescue functionality with the mobility typical of neck knives , offering high utility in tactical, urban and outdoor conditions. The liner lock mechanism-based design allows for easy opening and secure locking of the blade, while allowing for discreet carrying in a neck-hanging sheath. Blade made of 7Cr17MoV stainless steel is coated with black titanium, which reduces reflections, improves corrosion resistance and increases the durability of the working surface. The drop point blade form supports precision cutting and emergency work. Handle made of anodized aluminum in coyote color , was covered with a rubberized layer, which improves grip even in demanding conditions. In the back there are a glass breaker and belt cutter, making this model a versatile EDC and emergency tool. Thanks to its rigid Kydex sheath and chain, the RK-19652 will prove itself as a compact, everyday backup - always available and ready for action.
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 - drop point type is made of 7Cr17MoV stainless steel, known for its corrosion resistance and easy maintenance. The black titanium coating serves a protective function - it increases abrasion resistance, reduces reflections and gives the whole thing a modern, tactical look. The cutting edge is designed for precision tasks and emergency applications. A liner lock mechanism effectively locks the blade in the open position, ensuring safety during use and allowing the tool to be easily folded after use. The knife comes with a Kydex sheath with a neck chain for quick access and convenient carrying, regardless of the environment or situation.
Handle - made of anodized aluminum in coyote color , which guarantees low weight and resistance to wear. Rubberized surface improves grip in the hand, even in the presence of moisture or dirt. Ergonomic profiling provides comfort and control during handling, while rescue functions - a glass breaker and belt cutter - increase the knife's range of uses in emergency situations. Thanks to its compactness, the RK-19652 model is ideal for carrying around the neck or clipping into tactical equipment. It comes with a rigid Kydex plastic sheath with a ball chain, allowing you to carry the tool safely and discreetly. This is a versatile folder for users expecting reliability in a minimalist format.
