Ultratech D/E Red Aluminum, Satin is a full-size OTF (Out The Front) automatic knife from the Ultratech series. Featuring a hell of a fast extension mechanism with a razor sharp double edge blade in a striking Satin finish. 100% made and assembled in the USA. Designed by Anthony Marfione, knifemaker and owner of Microtech Knives.
Ultratech OTF Line - Microtech's flagship model in 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, the ability to open and close with one hand, the slim shape of the handle and the sharp blade make it a one-of-a-kind knife, available only from Microtech.
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 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 in a Dagger D/E (Double Edge) style, sharpened on both sides, finished with an elegant satin finish. The blade was brought out with a high 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 excellent precision in 3D technology on CNC milling machines, from red anodized 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.
