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.
Training Karambit 3D Skull, Black ABS, Blunt 3Cr13MoV (18713-A) is a professional karambit training knife, designed to simulate hand-to-hand combat techniques under controlled conditions. Thanks to the Blade's blunt blade and distinctive curved form, the model allows you to faithfully reproduce combat sequences, while maintaining full safety for practitioners. The construction is made of resistant 3Cr13MoV stainless steel, which guarantees rigidity and durability even under intensive use. The matte black finish and embossed skull motif enhance the visual character of the knife, referring to tactical design. The ABS plastic Handle has been shaped for ergonomics and features a classic finger ring, which increases control of the tool in any grip position. The liner lock and belt clip make the 18713-A a functional training accessory for those practicing systems such as Kali, Silat or Krav Maga. It's a realistic, balanced tool with an aggressive aesthetic, designed for training, learning and perfecting techniques with a karambit.
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 - Classified as a training tool, the blade is made of 3Cr13MoV stainless steel and has no sharp edge, significantly reducing the risk of injury during contact training. The carambit profile with a strongly marked curvature enables precise simulation of rotational sequences, typical of defensive and offensive techniques. The black finish and graphic skull motif add to the blade's distinctive look and aesthetic consistency with the rest of the blade. The thumb stud-based opening mechanism allows one-handed operation, while the liner lock guarantees stability in the open position. Blade design has been optimized for durability and realistic responses of the tool to varying loads during training.
Handle - made of black ABS plastic, the handle is characterized by low weight and resistance to mechanical damage. Its symmetrical shape, texture and the presence of a three-dimensional skull pattern not only improve the grip, but also give the knife a unique tactical character. The finger ring (finger ring) provides stability and allows smooth changes of grip - in accordance with the technique used in martial arts. The design is set on a steel frame, bolted together for greater durability. An additional clip allows the knife to be conveniently carried during training, without the need for a sheath. The Handle of the 18713-A model provides an ergonomic, safe and aesthetically refined solution for demanding users.
