Microtech Scarab II Gen III Executive D/E-S Tactical OTF Knife Tactical Black DLC Aluminium, Black DLC M390MK by Tony Marfione (1181-1T) M390MK by Tony Marfione (1181-1T)

Scarab II Gen III Executive D/E-S Tactical Black DLC Aluminum, Black DLC represents the pinnacle of excellence in automatic tactical knives, drawing inspiration from the original Microtech Ultratech design. Built to withstand the harshest conditions, the new Scarab II is the top choice for heavy-duty use. While retaining the stylistic features of its predecessor, it sets a new standard for OTF (Out The Front) technology.

Externally, it resembles the previous generation, but it is the internal design that makes the new Scarab II in a class of its own. The revolutionary dual blade deployment mechanism not only ensures smoother operation, making opening easier, but the dual-spring design propels the blade forward with enough force to open the knife even underwater. Precision-crafted to the highest standards, the Scarab II guarantees unmatched reliability and safety of use.

M390MK - thanks to the collaboration between Microtech and Böhler engineers, an exclusive version of M390 steel was developed exclusively for Microtech. The carbon content was increased and subjected to more rigorous control, thereby improving the properties of M390 steel to ensure better edge retention, corrosion resistance, and polishability. A martensitic high-performance chromium steel produced using powder metallurgy. Due to its alloy composition, it features exceptionally high wear resistance and high corrosion resistance. Thanks to its high wear resistance, it retains its edge shape well, allowing the blade to stay 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 19.0% (Cr), alloyed with 1.95% carbon (C) and 4.0% vanadium (V), hardened to a 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.

DLC (Diamond Like Carbon) – the blade’s surface durability is enhanced by a black, matte nanocomposite coating that exhibits unique properties such as exceptional hardness and low friction, as well as excellent corrosion resistance. It is one of the most scratch- and wear-resistant coatings used in industry, including the cutlery industry.

Blade - machine-ground D/E-S (Double Edge-SpearPoint), double-edged with a line of fuller grooves on both sides of the blade. The durability of the blade surface has been enhanced with a non-reflective, matte DLC coating, which exhibits unique properties: exceptional hardness, low friction, and excellent corrosion resistance. The blade features a high flat grind, ensuring excellent cutting performance. This allows the knife to maintain high strength while offering outstanding piercing capabilities. The robust blade extension/retraction mechanism, operated by a knurled Thumb Slide, a stepped thumb slide, requires a specific amount of force to overcome spring resistance for safety. In this model, the knurling has been upgraded to a version featuring a distinctive “X” in the center. The opening mechanism ensures smooth operation for both right- and left-handed users.

Handle - precision-machined using 3D technology on CNC mills from DLC-coated 6061-T6 aluminum. The back and bottom of the handle feature jimping for a more secure grip. The slim profile and the milled, two-position (right/left) solid deep carry clip allow for discreet carrying of the knife in a pocket in the tip-down position (blade tip pointing down). The clip features the scarab pictogram characteristic of this line. 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 threading a decorative cord.
