- Black Army Black Cord, Black – a compact outdoor knife with a fixed blade made of 3Cr13MoV steel, with a handle wrapped in black cord. Minimalist form and tactical finish – ideal for field and emergency tasks.

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.

3Cr13MoV is a martensitic chromium steel that has been enriched with molybdenum (Mo) and vanadium (V) to improve its performance properties. The typical chemical composition includes about 0.26-0.35% carbon (C), 12.5-14.5% chromium (Cr), 0.4-0.6% molybdenum (Mo) and 0.1-0.2% vanadium (V). The addition of chromium provides corrosion resistance, while molybdenum increases hardenability, high-temperature strength and resistance to pitting corrosion. Vanadium contributes to the hardness, wear resistance and fine grain structure of the steel. 3Cr13MoV is used for knives (often found in folding knives and hunting knives), medical tools and other applications where a good combination of corrosion resistance, hardness and strength is required. It is an improved version of 3Cr13 steel, offering better sharpness retention and overall durability.
Blade - made of 3Cr13MoV stainless steel, which provides corrosion resistance and ease of sharpening in field conditions. The clip point profile with a pronounced dagger allows for effective piercing and precise blade guidance in a variety of materials - from soft to hard plastics. The black finish reduces light reflections and protects the surface from scratches and weathering. The full tang design , increases the rigidity of the tool and resistance to stress when working under load. Blade is designed for universal field use, offering functionality in both utility tasks and emergency situations.
Handle - is an extension of the Blade's steel shaft, braided with tightly arranged black synthetic cord, which serves as both a grip enhancement and an emergency section of line in the field. The braided cord provides grip even in wet conditions, and the straight, symmetrical profile of the grip allows the knife to be operated in a variety of configurations - including with gloves. The transition between the Blade and Handle is smooth and free of sharp edges, which increases comfort during prolonged use. It comes with a sheath made of nylon, allowing you to securely attach the knife to your belt or gear. This Handle is designed for reliability, simplicity and versatility in field conditions.
