372,43 €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.
Dirac Delta D/E Black Aluminum, Apocalyptic is an enlarged OTF automatic knife from the Dirac series. Operating in D/A mode, it is equipped with a lightning-fast blade release mechanism. Slider button on the side of the handle. 100% manufactured and assembled in the USA. Designed by Anthony Marfione, knifemaker and owner of Microtech Knives.
Dirac Delta® is an enlarged version of the first OTF D/A (Double Action) automatic knife in the Microtech® range, equipped with a slider located in a recess on the side of the handle. This model has a modern, ergonomic handle with curved lines inspired by the iconic HALO® model. The Dirac Delta® series features Microtech®'s signature premium solutions – patented screws, an innovative internal mechanism, and a functional glass breaker. With a total length of 9.25 inches, the Dirac Delta® is an excellent choice as an everyday carry (EDC) knife.
M390 Microclean® - martensitic high-performance chromium steel produced by powder metallurgy. Due to its alloy concept, it is characterized by exceptionally high wear resistance and high corrosion resistance. Thanks to its high wear resistance, it retains its edge shape well, so the blade stays sharp for a very long time (requires minimal maintenance). Another advantage is its resistance to “wire” formation during sharpening. Steel with a high chromium content of 20.0% (Cr) with an admixture of 1.9% carbon (C), 4.0% vanadium (V), hardened in the range of 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 type, sharpened on both sides with a long line of blood grooves on both sides of the blade for reinforcement. Finished with Apocalyptic patina to mask scratches caused during use. The blade has a high flat grind, ensuring excellent cutting properties. Thanks to this, while maintaining high strength, the knife has excellent piercing properties. Centrally located blood grooves further reinforce the blade. The strong mechanism for extending/retracting the blade using a knurled Thumb Slide, a stepped slider under the thumb, 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 users.
Handle - made with excellent precision using 3D technology on CNC milling machines, from Mil-Spec coated aluminum 6061-T6. The texture of the handle surface prevents the knife from slipping in your hand during use. There are jimping on the back and bottom of the handle for a more secure grip. A distinctive feature is the location of the slider in a recess milled into the side of the handle. This allows the hand to rest more naturally when opening and closing the knife. The slim profile and milled two-position (right/left) solid deep carry clip allow the knife to be carried discreetly in a pocket in the tip-down position (with the tip of the blade pointing downwards). The clip features the Microtech logo, serial number, and date of manufacture. The handle is finished with a glass breaker, a solid steel triangle with a tungsten carbide ball pressed into it.
