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.
Daytona S/E Black Aluminum/3M, Apocalyptic P/S is a compact OTF automatic knife from the Daytona series. Designed for EDC applications, it retains all the advantages of larger models. Operating in D/A mode, it features a fast blade extension mechanism. Its Blade is made of excellent M390MK steel, which is the result of cooperation between two renowned companies - Microtech and Böhler. This steel is known for its exceptional strength and long holding of sharpness, so this knife is not afraid of any challenge.
Daytona - 85% Ultratech® sized, designed to fit perfectly in the hand, making it an excellent choice for everyday carry. The release mechanism is easier to operate than the full-size Ultratech® and is ideal for smaller or sensitive hands. The Daytona® still has the full-featured glass breaker and all the features of the full-size Ultratech®. A distinguishing feature is an inlay on the handle made of a different material which, in addition to its decorative function, improves grip security.
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 to provide 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 - machine ground S/E (Single Edge Drop Point) type, one side sharpened, partially serrated (P/S). Finished with a striking patination using the Apocalyptic method. The blade is brought out with a high flat grind (Flat Grind), providing excellent cutting properties. As a result, the knife has excellent piercing properties while maintaining its strength. The strong mechanism of extending / retracting the blade with the help of a moled Thumb Slide, a stepped slide under the thumb requires for safety the application of a specific force to overcome the resistance of the spring. The method of opening provides seamless opening for both right and left-handed people.
Handle - made with perfect precision in 3D technology on CNC milling machines, from 6061-T6 aluminum coated with Mil-Spec Hard Coat. Perfectly fitted inlays (inlay) of special 3M Traction Tape material with sandpaper texture make 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. The slim profile and milled two-position (right/left) solid deep-carry clip allow the knife to be carried discreetly in a pocket, in tip-down (blade tip down) position. The clip bears the Microtech logo and production date. The Handle is finished with glass breaker, a solid steel triangle, into which a tungsten carbide ball has been pressed. It also features a hole for interweaving a decorative cord.
