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 cooperation of Microtech and Böhler engineers, an exclusive version of M390 steel has been created, made only for Microtech. The carbon content has been increased and subjected to more precise control, improving the properties of M390 steel to ensure better edge retention, corrosion resistance and polishing. Martensitic high-performance chromium steel produced by powder metallurgy. Due to the alloy concept, it is characterized by an extremely high wear resistance and high corrosion resistance. Thanks to the high wear resistance, the shape of the edge is properly maintained, so that the blade remains sharp for a very long time (requires minimal maintenance). Another advantage is the resistance to “wire” formation during sharpening. Steel with a high chromium content of 19.0% (Cr) with an admixture of 1.95% carbon (C), 4.0% vanadium (V), hardened to 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 Bayonet type, finished with a Stonewashed method to mask fine scratches caused during use. The blade has a high flat grind, which ensures excellent cutting properties with a central grain. This gives the knife excellent piercing properties while maintaining high durability. The strong blade extension / retraction mechanism with a knurled thumb slide 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 people.
Handle - made with high precision in 3D technology on CNC milling machines, from sand-blasted anodized aluminum 6061-T6. The surface texture of the handle ensures that the knife does not slip in the hand during use. The handle has jimping on the back and bottom for a secure grip. Slim profile and two-position (right/left) pocket clip milled from titanium, allowing the knife to be carried in a tip-down position. Equipped with a smooth rollerball, thanks to which the knife easily slides into a pocket without damaging the edges.
