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.
Mini Troodon D/E Black Aluminum, Black is a compact version of the OTF (Out The Front) automatic knife from the Troodon series. Equipped with a hell of a fast mechanism that extends the razor-sharp blade. The main focus is on ease of portability while maintaining the ergonomics of the larger version. 100% made and assembled in the USA. Designed by Anthony Marfione, knifemaker and owner of Microtech Knives.
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 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.
Blade - machine ground D/E (Double Edge Dagger) type, sharpened on both sides with one edge F/S (Full Serrated) and the other Plain. Coated with a black protective coating. The blade is brought out with a high flat grind (Flat Grind), providing excellent cutting properties. As a result, the knife has excellent piercing properties while maintaining its strength. The centrally placed grain further strengthens the blade. 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 black anodized 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 the 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. The clip bears the Microtech logo, serial number and production date. The Handle is finished with a glass breaker, a solid steel triangle, into which a tungsten carbide ball has been pressed. It also features a hole for interweaving a decorative cord.
