RK-31824 Grey Aluminum, Black Titanium is a tool designed for maximum functionality and reliability in the field. Equipped with a Blade made of 7Cr17MoV steel , this knife offers ruggedness, corrosion resistance and ease of maintenance, making it a reliable support for outdoor and operational activities. The Black Titanium coating eliminates reflections and enhances surface abrasion resistance, while providing a discreet aesthetic in keeping with the tactical nature of the design. The partially serrated blade allows for effective cutting through fibrous materials, increasing its usefulness in emergency and technical situations. The lightweight yet rigid anodized aluminum Handle has been ergonomically contoured and equipped with perforations to improve grip, which translates into a secure grip even in harsh weather conditions. It comes with a MOLLE-compatible sheath, guaranteeing quick access and safe carrying of the knife. The 31824 is a precision-engineered tool for users who expect functionality, durability 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 - made of 7Cr17MoV stainless steel, clip point profile with partial serrations, which provides versatility of use - from precision cuts to quick punctures and cutting through ropes or belts. The Black Titanium coating has an anti-reflective effect and increases surface resistance to abrasion and corrosion. The grind allows the blade to run smoothly, which is important in the context of tactical and rescue operations. The design has been optimized for durability and functionality in a dynamic operational environment.
Handle - made of anodized aluminum in a shade of tactical gray combines mechanical resistance with lightness and aesthetics. The perforated structure and ergonomic profiling ensure a secure grip even in the presence of moisture, mud or dust. Thanks to its sheath made of nylon with the MOLLE system, the knife can be easily clipped to your equipment for instant access and safe storage. This is a rugged tool designed for heavy use in field and tactical conditions.

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.
