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-32330 Neck Knife Titanium from the K25 brand is a lightweight utility neck knife with a minimalist, highly functional design, dedicated to users looking for a tool for lightning-fast and precise action. With a wharncliffe blade and full tang construction , this model offers exceptional durability and effectiveness for tasks requiring reliability - both in everyday use and in emergency situations. The 7Cr17MoV stainless steel guarantees corrosion resistance and ease of sharpening, while the titanium-based coating used reduces glare and increases surface resistance. The open, skeletonized Handle grips without grips allow individual personalization of the grip - for example, by braiding with paracord cord - and reduce the overall weight of the tool. The set is completed by a kydex sheath with a neck chain, allowing quick access and safe carrying in discreet mode. This is a tactical tool for those who focus on reliability, mobility and efficiency in any situation.
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 - with a wharncliffe profile was made of 7Cr17MoV stainless steel and coated with a titanium-based matte coating , providing increased wear resistance and reduction of light reflections. With a straight cutting edge and flat grind, the wedge allows for precise blade guidance, which is important for everyday use. The compact format and full tang construction guarantee high rigidity and no weak points, which translates into confident performance under stress.
Handle - the skeletonized handle integrated into the blade offers low weight and full customization - the user can wind tape, leather or paracord, customizing the grip to individual preference. Technological holes reduce weight and improve hand ventilation, and the symmetrical geometry allows the knife to be operated comfortably regardless of the grip. The lack of grips simplifies maintenance and enhances the rugged, tactical look of the overall design. It comes with a lightweight kydex she ath equipped with a chain, which allows you to carry the knife around your neck - always at hand, always ready for action. An ideal choice for those who value discretion, mobility and efficiency.
