466,85 €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.

With an overall length of 9.25 inches, the Dirac Delta® is an excellent choice as an everyday use knife (EDC).
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 - a machine-ground D/E (Double Edge) Dagger profile, sharpened on both sides and featuring a long fuller on each side to reinforce the construction. The durability of the blade surface is enhanced by a non-reflective, matte nanocomposite Black Finished coating, characterized by exceptional hardness, low friction, and excellent corrosion resistance. The blade is ground with a high flat grind, providing outstanding cutting performance. Combined with the robust construction, this gives the knife excellent piercing capability. The centrally positioned fuller further strengthens the blade. The strong deployment and retraction mechanism is operated via a knurled, stepped Thumb Slide. For safety, it requires noticeable force to overcome the spring tension. The opening method ensures smooth and reliable operation for both right- and left-handed users.
Handle - made with excellent precision in 3D technology on CNC milling machines, from Mil-Spec coated aluminum 6061-T6. The surface texture of the Handle makes the knife non-slip in the hand during use. There are notches (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 lay more naturally when opening and closing the knife. 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 glass breaker, a solid steel triangle, into which a tungsten carbide ball has been pressed.
