732,81 €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.

M390MK - thanks to the collaboration between engineers from Microtech and Böhler, 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.
Ram-Lock (Crossbar Lock) – a crossbar that moves horizontally within longitudinal slots in the steel side plates of the handle frame. When the knife is opened, the locking bar engages from above onto the rear part of the blade, preventing it from moving back. This bar is pressed down by two springs. Unlocking occurs by pulling the locking bar backward; its ends are accessible through cutouts in the side plates of the handle. In the closed position, the bar presses against a cam surface at the rear of the blade, preventing it from opening spontaneously. The advantages of the Ram-Lock mechanism include resistance to contamination, practical insensitivity to dynamic loads, ease of operation with both the right and left hand, and smooth operation.
Blade - machine-ground Drop Point style, single-edged S/E (Single Edge). Finished with a Bronzed Stonewashed finish that masks minor scratches caused by use. It opens using the model’s signature dual thumb studs—teardrop-shaped, knurled pins on both sides of the handle—making it easy to use for both right- and left-handed users. Ball bearings ensure the opening mechanism operates smoothly. The blade features a high flat grind, providing excellent cutting edge geometry and extreme cutting performance. To maintain full control over the blade, the blade spine features upper jimping, a serrated thumb rest. The entire unit is secured with a convenient Ram-Lock.
Handle - made of durable titanium, covered with a distinctive texture imitating the surface of shrapnel (Frag Pattern) for a better grip. The wide lock slider features Microtech’s signature stepped X pattern. Both scales are secured with a solid, bronze-colored titanium backspacer. A reversible (right/left) titanium clip allows for discreet tip-up carry. Above the clip is a lanyard hole for a safety or decorative cord.
