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.
Hero Olive Wood, Satin is a compact premium folding knife designed by acclaimed Italian designer Tommaso Rumici. This model was created for users who expect durability, functionality and elegant design in an EDC format. The design combines modern materials, tactical details and Italian precision craftsmanship, offering a tool ready for everyday use in varied conditions. Blade made of Böhler M390 powder-coated steel provides excellent performance - from excellent sharpness retention to full corrosion resistance. The satin finish masks wear marks and emphasizes the practical, technical nature of the blade, allowing it to be used extensively for both precision and more demanding tasks. Handle grips based on olive wood grips have been supplemented with titanium bolsters, which increases the rigidity and durability of the design while maintaining a compact form. The structured surface of the material provides a secure grip in a variety of conditions, and the ergonomic profiling supports the comfort of handling the tool. The whole is complemented by the backlock mechanism, known for its reliability and secure immobilization of the blade during work. The Hero model is for those who expect the highest quality workmanship, versatility and modern design in a compact EDC format.
Tommaso Rumici is a knife enthusiast who has been associated with the Italian magazine “Coltelli” since 2009. His passion and knowledge led to his 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), 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.
Blade - Drop Point type with clearly marked belly, finished with elegant satin finish. The solid thickness of the blade combined with a high, flatgrind) gives an excellent cutting edge geometry and extreme cutting performance with high durability. Ball bearing system aids smooth opening of the blade, which can be opened with thumb studs on both sides . Locking mechanism Back Lock. On the back of the Blade notched upper jumping thumb rest .
Handle - 6AL4V titanium bolsters , olive wood handle. Chamfered edges of the covers eliminate sharp edges.
