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.
H2 Karambit G10 Black, Black Stonewashed is a compact fixed blade knife from Italian brand LionSteel, designed by Tommaso Rumici for users looking for a dynamic, lightweight and uncompromisingly functional tool. The design belongs to the H-Series, which combines precise design with modern materials and tactical aesthetics. The Böhler M390 powder-coated steel blade provides exceptional edge durability, corrosion resistance and stability even under heavy use, while the black stonewashed finish emphasizes the tool's rugged, utilitarian nature and masks traces of use. The carambit profile, combined with the finger ring, allows for quick draw and full control in all conditions - both during precision cuts and in the context of defensive applications. Handle made of G10 has been optimized for reverse grip and gloved work, while offering the rigidity of full tang construction . The whole creates a tool that is ready for urban and tactical environments - for professionals and enthusiasts of EDC knives , who do not accept compromises.
Tommaso Rumici is a knife enthusiast who has been associated with the Italian magazine “Coltelli” since 2009. His passion and knowledge led to a collaboration with Viper as the designer of the Fearless knife, limited to 300 copies and now highly sought after by collectors around the world. In the following years, he was able to expand his activities as a designer by establishing collaborations not only with Viper, but also with other major brands. Tommaso is passionate about knives in general, but is most fond of outdoor-military blades.
M390 - a 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), hardened between 59-61 HRC, vacuum and cryogenic treatment and double tempering. This super steel is comparable to Carpenter's CPM 20CV or CTS-204P steels. Manufactured by Böhler Edelstahl in Kapfenberg, Austria.
Blade - karambit, based on a modified drop point form, was designed for pull cuts and precision close contact work. The centrally set tip, curved cutting edge and finger hole provide exceptional blade control in dynamic situations. Powdered M390 steel, considered one of the most advanced premium tool steels - offering excellent sharpness retention, abrasion resistance and total stainless steel - is used. The flat grind (flat grind) allows for smooth cutting with low material drag, while maintaining the Blade's rigidity. The black stonewashed finish gives the blade a matte, anti-reflective look and reduces the visibility of scratches, which is crucial for everyday tactical use. Blade is supported by full tang construction , which increases resistance to overloading and allows full control of the tool without compromising on durability.
Handle - made of black G10, a fiberglass-based laminate, provides resistance to impact, moisture and changing weather conditions. The surface texture has been precisely milled, which increases hand grip even when wearing work gloves or with wet hands. The ergonomic profile includes pronounced finger supports, and the integrated tactical ring improves stability during dynamic operations and allows for instant retrieval of the knife. Thanks to the full tang construction , the whole design is characterized by high rigidity and durability, making it resistant to mechanical damage even under intensive use. The H2 model is compatible with a Kydex sheath , allowing it to be carried in various positions - horizontally, vertically or in MOLLE systems . It is an ergonomic and durable solution for users who need a tool that is reliable, compact and fully functional - both in everyday EDC, as well as in tasks of a tactical nature.
