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-32693 Boot Knife Rubber Black, Titanium/Brushed is a tool designed for intensive tactical, training and defensive operations. The symmetrical dagger blade is made of 3Cr13MoV stainless steel, known for its corrosion resistance and ease of sharpening. Its surface is coated with a titanium-based coating, which reduces glare and increases abrasion resistance. Blade's balanced geometry and grind allow for precise cuts and deep penetration, essential in emergency situations. A key element of the design is the finger ring, allowing the blade to rotate around the finger - a feature particularly valued by self-defense instructors and tactical professionals. The rubber handle offers a secure grip even in harsh weather conditions, and the Quick Release Sheath provides instant access to the knife. It's a complete solution for those who want precision, durability and instant response - without compromise.
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 made of 3Cr13MoV stainless steel and finished in a striking Two Tone method, with the blades coated, the rest of the blade brushed. The dagger profile and single-sided flat grind allow for effective piercing, cutting in multiple directions and dynamic handling of the tool. The balance of the blade was chosen to provide full control during fast movements and ensure stability in the hand. Blade's shape allows defensive, tactical and utility applications, and its strong construction strengthens the entire structure.
Handle - made of black textured rubber, providing a secure grip in all conditions and resistance to dirt and abrasion. Ergonomic profiling improves user comfort, reducing hand fatigue during prolonged activities. The integrated finger ring supports advanced blade rotation techniques. It can also be used to mount a line. The sheath comes complete with a black nylon she ath with Quick Release system and the ability to attach to a belt or a mount. This is a practical, modern design that meets the needs of users operating in stressful conditions, requiring quick access and maximum functionality.
