K25 RK-18488 Knife Black Aluminum, Black 7Cr17Mov
- RK-18488 Black Aluminum, Black - compact EDC folding knife with black 7Cr17MoV steel blade and anodized aluminum handle. Slim, lightweight, tactical - ideal for discreet carry and everyday use.
RK-18488 Black Aluminum, Black is a minimalist EDC folder designed for users looking for a lightweight, slim and functional everyday tool. The design is based on proven geometry, good quality 7Cr17MoV stainless steel and a durable anodized aluminum handle - all encased in a modern, tactical aesthetic. The blade's surface has been treated with a black coating to increase corrosion and abrasion resistance, while eliminating light reflections. Thanks to its slim profile and light weight, this model is perfect for discreet carrying - either loose in a pocket or clipped on with a steel clip. The black anodized aluminum Handle was designed with ergonomics in mind - subtle milling and rounded edges provide comfort and grip stability, even in dynamic situations. The whole is complemented by a classic liner lock, which allows safe and intuitive one-handed operation. The 18488 Folder is an excellent choice for those who appreciate lightness, reliability and functionality in everyday use.
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, known for its good corrosion resistance, moderate hardness and ease of sharpening - qualities ideal for knives used every day. The drop point profile allows for versatile use, combining precision cutting capabilities with adequate structural strength. The coating acts as a protection against wear marks, improves anti-reflection properties and emphasizes the modern, technical look of the blade. The applied flat grind enables smooth, controlled cutting with low material resistance, which translates into comfort in both delicate tasks and more demanding operations. The entire blade design has been optimized for everyday use - compact dimensions, ergonomic profile and uniform finish create a practical, reliable tool for everyday carry in urban and tactical environments.
Handle - made of anodized aluminum, a material that combines low weight with good rigidity and wear resistance. The black anodized surface provides additional protection against corrosion and gives the entire design a subdued, professional look. The matte texture improves grip, while subtle milling promotes sure grip regardless of environmental conditions. The liner lock used is a classic locking mechanism, which increases the safety of use and allows the knife to be operated efficiently with one hand. In the front part of the Handle there is a tip-up clip, which allows you to discreetly and conveniently carry the folder in your pocket or at the belt. The design of the 18488 is a harmonious combination of strength, lightness and functionality - an ideal choice for those looking for a compact EDC knife in a modern, tactical form.

Przeczytaj!
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.
