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.
Combat Troodon Gen III D/E Black Aluminum, Tactical P/S the largest of the automatic knives, is the pinnacle of precision engineering and tactical efficiency in the field of OTF (Out The Front) knives. Built for a wide range of uses, it is 25% larger than the flagship Troodon. Precision-crafted, equipped with a sophisticated and extremely fast retractable mechanism and a razor-sharp blade. 100% made and assembled in the USA. Designed by Anthony Marfione, knifemaker and owner of Microtech Knives.
Combat Troodon OTF Line - Troodon means “tooth harmer” in Greek. Although this name was first given to a dinosaur similar to a raptor, it is equally suitable for Microtech's large OTF knife, which was designed for all-purpose use and close combat. This automatic knife with above-average durability and D/A (Double Action) mode is a favorite OTF among law enforcement officers, the US armed forces, and emergency service personnel. Its robust design makes the Combat Troodon® suitable for intensive use, and the advantages of the Out The Front automatic knife also make it an excellent knife for everyday use.
M390MK - thanks to the cooperation of Microtech and Böhler engineers, an exclusive version of M390 steel has been created, made only for Microtech. The carbon content has been increased and subjected to more thorough control, improving the properties of M390 steel to ensure better edge retention, corrosion resistance and polishing. A martensitic high-performance chromium steel produced using powder metallurgy. Due to the alloy concept, it is characterized by extremely high wear resistance and high corrosion resistance. Due to its high wear resistance, it keeps its edge well, which means that the blade stays sharp for a very long time (minimal maintenance required). Another advantage is that it is resistant to “wire” formation during sharpening. Steel with a high chromium content of 19.0% (Cr) with an admixture of 1.95% carbon (C), vanadium 4.0% (V), 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) Dagger, sharpened on both sides, both edges partially P/S (Partial Serrated) serrated, with a long line of chip grooves on both sides of the blade. It is characterized by an effective Tactical finish, the cutting edges and the fuller are covered with a black coating, the rest of the blade is satin finished. The blade is produced with a high flat grind, which ensures excellent cutting properties. This gives the knife excellent piercing properties while maintaining high strength. The wide grain additionally strengthens the blade. A strong blade extension / retraction mechanism with a knurled thumb slide requires a certain amount of force to overcome the spring resistance for safety reasons. The opening method ensures trouble-free opening for both right- and left-handed people.
Handle - made with high precision in 3D technology on CNC milling machines, from Mil-Spec coated aluminum 6061-T6. In the Tactical version, all hardware (screws, clip, slider) is deep black. The surface texture of the handle and the deep jimping on it ensure that the knife does not slip in the hand during use. The slim profile and milled two-position (right/left) solid deep carry clip allow the knife to be carried discreetly in the pocket in a tip-down position (with the tip of the blade facing down). Equipped with a smooth rollerball, thanks to which the knife easily slides into the pocket without damaging the edges of the pocket. The clip features the Microtech logo and date of manufacture. The handle is finished with a steel triangle window breaker with a pressed-in tungsten carbide ball.
