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 Interceptor Gen III Signature Red Aluminum, Stonewashed this largest of automatic knives is the pinnacle of precision engineering and tactical prowess in the field of OTF (Out The Front) knives. Built for a wide range of utility applications, it boasts a 25% larger size compared to the flagship Troodon. Precisely crafted with a sophisticated and hellishly fast ejection mechanism for the razor-sharp new type of blade - the Interceptor. 100% made and assembled in the USA. Designed by Anthony Marfione, knifemaker and owner of Microtech Knives.
Combat Troodon OTF Line - Troodon means “wounding tooth” in Greek. Although the name was first given to a Raptor-like dinosaur, the name is equally appropriate for Microtech's large OTF knife, designed for all sorts of uses and close combat. The over-the-top,Double Action (D/A) automatic knife is a favorite OTF among law enforcement officers, US armed forces and emergency services personnel. Its rugged construction makes the Combat Troodon® suitable for heavy use, and the advantages of the Out The Front automatic also make it an excellent knife for everyday carry.
Signature Series - an elite line of Microtech products designed for buyers who are looking for a more exclusive touch to the much-loved Core Series production models (logo with claws on the knife). Top-quality materials and finishes are often used in the production of Signature Series knives. The line also includes themed knives such as Bounty Hunter, Memento Mori and Molon Labe. A distinctive feature is the marking with the dagger logo on the Handle and Anthony Marfione's signature on the clip.
M390MK - thanks to the cooperation of Microtech and Böhler engineers, an exclusive version of M390 steel made only for Microtech was created. The carbon content has been increased and subjected to closer scrutiny thus improving the properties of M390 steel for 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 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 - machine-ground, single-sided sharpened Interceptor type, with characteristic “teeth on the back and false blade, finished with a scratch-masking bath of fine Stonewashed pebbles . The blade is brought out with a high Flat Grind for excellent cutting qualities. Thanks to this and the wide grain, while maintaining high strength, the knife has excellent piercing properties. The strong mechanism of extending / retracting the blade with the help of the moled Thumb Slide, a stepped thumb slide requires for safety the application of a specific force to overcome the resistance of the spring. The method of opening provides seamless opening for both right and left-handed people.
Handle - made with excellent precision in 3D technology on CNC milling machines from 6061-T6 Aluminum. The surface texture of the Handle and the deep notches (jimping) on it make the knife non-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 tip-down (blade tip down) position. Equipped with a smooth rollerball, which allows the knife to slide easily into the pocket without damaging the pocket edges. The clip bears Anthony Marfione's signature and the date of manufacture. The Handle is finished with glass breaker, a tungsten carbide ball.
