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.
USMC pattern Ka-Bar Brown Leather, Black was created for lovers of military classics, offering a combination of traditional design and full-fledged field functionality. Referring stylistically to the legendary Ka-Bar knife used by the armed forces, this model offers proven construction, solid stainless steel and a handle made of leather, ring-molded in the manner known from classic combat tools. Blade made of 3Cr13MoV steel is coated with a black protective coating, reducing light reflections and increasing the blade's resistance to abrasion. The clip point profile promotes precise and dynamic cuts, making the knife suitable for both field work and emergency applications. The blade's straight geometry and flat grind allow for convenient cutting guidance and easy tool care. The compressed eco-leather Handle offers an excellent fit in the hand, even in harsh conditions - wet, cold or when working with gloves. A metal head allows the tip to be used as a hammer or nailer. The set is completed with a leather sheath, allowing comfortable carrying at the belt. The 31762 model is an excellent choice for collectors, EDC users who appreciate vintage aesthetics and enthusiasts of classic field equipment.
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 - is based on the classic clip point profile , which provides excellent penetration properties and precise blade guidance. The 3Cr13MoV stainless steel is characterized by good corrosion resistance and ease of sharpening, which works well in heavy field use. The black coating protects the blade from abrasion, masks reflections and emphasizes the tactical nature of the knife. The flat grind promotes cutting efficiency while maintaining control over the depth of the blade. The entire blade is based on a classic design, which ensures high structural stability and resistance to overloading.
Handle - made of layered pressed organic leather provides a classic look and excellent ergonomics. The process of pressing the rings creates a durable, well-ventilated structure that adapts to the shape of the hand, while reducing slippage when working in demanding conditions. The material does not soak up water easily, and its texture remains adherent even in high humidity. The back of the Handle is finished with a metal head, which can serve as an emergency nailing or improvised striking tool. The whole is complemented by a leather sheath, adapted for mounting at the belt, offering quick access to the tool. This is a classic, functional Handle in the spirit of military traditions.
