- Black aluminum, black/satin automatic cutter OTF (Out The Front) in D/A (Double Action) mode. Blade made of 3Cr13MoV stainless steel, straight, comfortable aluminum handle. Robust design, reliable operation and reasonable price. A bestseller!

The Dulotec OTF Black Aluminum, Black/Satin 3Cr13MoV K190A-BK is a precision-engineered tool that combines modern aesthetics with functionality. The OTF (Out The Front) mechanism allows the blade to be quickly extended and retracted with a slider, ensuring quick access and safe use. The 3Cr13MoV stainless steel blade is highly corrosion resistant and easy to sharpen. Its symmetrical, double-edged dagger-type blade has a two-tone finish, with the bevels coated in black and the rest satin-finished, which emphasizes the precision of the workmanship. The handle is made of black anodized aluminum and provides a secure grip thanks to its textured surface, which prevents the hand from slipping. The two-position clip allows the knife to be carried in a tip-down position, according to the user's preference. The screw that secures the clip also serves as a window breaker, which increases the tool's functionality in emergency situations. The set includes a nylon case with a DuraFlex buckle for safe transportation of the knife. Robust design, reliable operation and an attractive price make the K190A-BK an excellent choice for users who value quality and functionality.
3Cr13MoV - martensitic tool steel, 13.0% chromium (Cr) content with excellent hardness and strength. By adding 1.0% manganese (Mn), 0.6% nickel (Ni) and 1.0% silicon (Si) to 3Cr13, an improvement in strength and hardness in the range of 52-55 HRC was achieved. Easy to sharpen, widely used in the production of knives, scissors and medical equipment.
Blade - slim and extremely sharp Dagger type with a double-edged symmetrical blade, finished with an effective Two Tone method, the cuts are covered with a black coating, the rest is satin-finished. Plain blade, with a raised flat grind, ensuring excellent cutting properties. There is a false edge at the top of the blade. This gives the knife excellent piercing properties while maintaining high strength. The blade deploys and retracts via a knurled slider that requires a certain amount of force to overcome the resistance of the spring. The opening mechanism allows for smooth opening for both right- and left-handed users.
Handle - made of black anodized aluminum, textured for a better grip. The slim design allows the knife to be stored in any pocket. The two-position clip (right/left) allows the knife to be carried in a tip-down position. The screw that secures the clip also acts as a glass breaker.
Sheath - a DuraFlex nylon carrying case with a buckle is included.
