504,90 €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.
Hera II D/E Black Aluminum, Tactical one of the most versatile OTF (Out The Front) automatic knives. Inspired by the iconic Troodon, it bridges the gap between EDC models and fully tactical designs. The exceptionally durable D/A (Double Action) mechanism provides fast, powerful, and reliable blade deployment and retraction. The knife stands out with its excellent fit, finish, and overall build quality. A design by Anthony Marfione, renowned knifemaker and owner of Microtech Knives.
Hera Series – tactical OTF knives that perfectly balance functionality and aesthetics. The models are available with D/E and S/E blade configurations, and feature handles made from aircraft-grade anodized aluminum. A unique feature of the Hera series is its precisely machined titanium pocket clip, equipped with a smooth rollerball, allowing for exceptionally easy and fluid insertion into any pocket.
M390MK - a collaboration between Microtech and Böhler engineers resulted in an exclusive version of M390 steel made only for Microtech. The carbon content has been increased and subjected to closer scrutiny thus improving the properties of M390 steel to provide better edge retention, corrosion resistance and polishing. Martensitic high-performance chromium steel produced by powder metallurgy. Due to its 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 19.0% (Cr) doped with 1.95% carbon (C), vanadium 4.0% (V), and is hardened to 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 - machine-ground D/E (Double Edge) with a Dagger profile. Its surface durability is enhanced by a non-reflective, matte nanocomposite Tactical Finished coating, known for exceptional hardness, low friction, and excellent corrosion resistance. The blade features a striking Two Tone finish - the grinds and fuller are coated black, while the rest of the blade is satin-finished. The high flat grind with a central fuller provides excellent cutting performance while maintaining high strength, and the overall geometry significantly improves piercing capability. The powerful deployment/retraction mechanism is operated via a textured Thumb Slide - a stepped thumb actuator that requires deliberate pressure to overcome the spring tension for safe use. This mechanism ensures secure, smooth, and intuitive operation for both right- and left-handed users.
Handle - crafted with the highest precision using 3D CNC machining, from black anodized 6061-T6 aluminum. The stepped surface texture ensures a secure grip and prevents the knife from slipping during use. Jimping on the spine and bottom of the handle provides even better control. The slim handle profile and machined titanium, two-position (right/left) pocket clip allow for tip-down carry (blade tip down). The clip is equipped with a smooth rollerball, allowing the knife to slide into a pocket easily and smoothly without damaging the pocket edges.
