Microtech OTF Ultratech D/E Navy Blue Aluminium, Stonewashed M390 by Tony Marfione (122-10NA)

TheUltratech D/E Navy Blue Aluminum, Stonewashed is a full-size OTF automatic knife from the Ultratech series, notable for both its functionality and aesthetics. Operating in D/A (Double Action) mode , it allows you to instantly extend and retract the blade with a single thumb movement, an extremely practical tool for situations requiring a quick response. Blade made of Böhler M390 steel , known for its exceptional corrosion resistance and excellent cutting edge retention, provides unparalleled cutting performance. The Handle, precision-crafted from Mil-Spec hard-coated aluminum in navy blue, is characterized by high strength and lightness, which significantly contributes to the comfort of use. The ergonomic shape of the Handle and textured surfaces ensure a secure grip, even in difficult conditions. In addition, the knife is equipped with a steel clip and glass breaker, which increases its functionality in emergency situations. The design by Tony Marfione, owner of Microtech Knives, combines modern design with the highest quality workmanship, making Ultratech Series knives a must-have tool for both collectors and professionals who value reliability and elegance.

Ultratech OTF Line - Microtech 's flagship model of the OTF line , which set the standard for all Out The Front knives. Ultratech 's proprietary trigger spring design, which remains in the “resting” position at all times, except when used. This prevents the spring from fatigue, reducing wear and tear on the internal trigger mechanisms which ensures that the knife will always function effectively. The light weight, one-handed opening and closing capability, slim Handle shape and sharp blade make this a one-of-a-kind knife available only from Microtech.

M390 Microclean® - martensitic high-performance chrome 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 20.0% (Cr) doped with 1.9% 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 Dagger D/E (Double Edge) type, sharpened on both sides. Finished masking minor scratches with a bath of Stonewashed pebbles . 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 thumb slide requires for safety to apply 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 excellent precision in 3D technology on CNC milling machines, from Mil-Spec hard-coated 6061-T6 aluminum. 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. The slim profile and 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 a 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.
