490,73 €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.
LKU01 Tenebra Carbon Fiber, Black DLC is a limited edition folding knife designed in collaboration with Danilo Rossi, creator of the Italian fighting style Lajolo di Cossano. Created in an edition of 100 pieces, this model combines tactical precision with a deeply rooted fighting philosophy to create a tool of exceptional functionality and collector value. The design of the folder with the possibility of transformation into a push dagger reflects the tenets of dynamic self-defense, where versatility, speed and reliability count. Blade is made of Böhler M390 steel , one of the most advanced premium powder steels. Thanks to its excellent sharpness holding, corrosion and abrasion resistance , the blade retains its performance even under heavy use. The Black DLC coating used enhances surface wear resistance and minimizes light reflections, giving the whole thing a tactical feel. The unusual geometry of the blade allows for effective cutting both in the classic grip, as well as in the piercing position. Handle made of carbon fiber in Tenebra finish provides high rigidity with minimal weight and elegant, technical aesthetics. The profile has been developed for tactical grips - both classic and vertical - allowing quick transitions between modes. The innovative Handle mounting system allows for a configuration that suits a specific use scenario. Model LKU01 Tenebra is a proposal for professionals, enthusiasts of modern combat systems and collectors, who expect from the knife not only precision, but also a deeper conceptual layer - a synthesis of applied tactics and movement school of thought.
Danilo Rossi is a very interesting figure in the world of martial arts. A direct descendant of the Lajolo family of Guelphs and Gibelins, he is an Italian nobleman of the Lajolo family and the son and nephew of the Lajolo Cossano counts of Piedmont, Italy. A stuntman, a raconteur, a lover of good cigars and whiskey, and a passionate champion of traditional Italian knife fighting methods. Based on his experience, he created the Lajolo di Cossano style, which combines elements of traditional fencing with a modern way of fighting. Limited production of the knife designed by Danilo Rossi was undertaken by one of the icons of the knife world, the company Extrema Ratio. In this way, the tradition of fighting knives was combined with contemporary design, and the whole thing produced a wonderful effect!
M390 - martensitic high-performance chrome steel produced by powder metallurgy. Due to the alloy concept, it has extremely high wear resistance and high corrosion resistance. Due to its high wear resistance, it adequately maintains the shape of the edge, so the blade stays sharp for a very long time (requiring minimal maintenance). Another of the advantages is resistance to the formation of “wire” during sharpening. The steel has a high chromium content of 20.0% (Cr) doped with 1.9% carbon (C), vanadium 4.0% (V), and is hardened between 59-61 HRC. This super steel is comparable to Carpenter's CPM 20CV or CTS-204P steels. Manufactured by Böhler Edelstahl in Kapfenberg, Austria.
DLC (Diamond Like Carbon) durability of the blade surface is enhanced with a matte black nanocomposite coating, which exhibits unique properties such as exceptional hardness and low friction, as well as excellent corrosion protection. It is one of the most resistant coatings to scratches and abrasion that are used in the industry, including the knife industry.
Blade - classic spear point, with a high flat grind that will provide excellent cutting properties. A “false blade” has been added to the top, making the knife much easier to penetrate any material. It opens with a disk (thumb disc) on the back of the blade, which allows seamless use by both right and left-handed people . The blade has been coated with a black DLC coating . The whole is locked with the proven and popular liner lock.
Handle - is Carbon Fiber composite. The grips have been bolted to a steel frame, which together gives tremendous strength to the construction. Instead of a standard backspacer, there is a spacer in the back between the skeleton of the structure . This solution provides easy access to the interior which is of considerable importance when cleaning the knife in the field. A two-position (right/left) stainless steel clip allows us to carry the knife in tip-down position .
