The Microtech Ultratech OTF knife is the biggest selling out the front knife on the market. The Ultratech automatic is the flagship model of Microtech Knives OTF (out the front) automatic lineup and sets the standard for OTF (out the front) technology. It has been the gold standard in OTF knife technology for over a decade. The most popular of the Microtech switchblades, the Ultratech is a D/A (double action) OTF knife that fires and retracts with the slide of a thumb. The thumb slider is located on the side of the handle making it extremely comfortable and normal to operate ergonomically. Proprietary technology allows the firing spring to remain "at rest" in both the open and closed positions, drastically reducing wear on the internal firing mechanism which is a huge safety feature (eliminating the risk for accidental firing) and durability solver for the double action knife. The contoured 6061 T6 aluminum handle provides a lighter and more ergonomic feel and comes in a smooth, flat finish. The Ultratech comes with glass breaker to be used in emergency situations located at the butt of the handle. Handle length is 5" and the blade is 3.35" long with a weight of just 3 ounces. The Microtech Ultratech is for sale in a variety of handle colors including black, green, tan, orange, blue, turquoise, and a number of high end finishes like copper and brass. The blade styles are D/E (Double Edge Dagger), S/E (Drop Point), T/E (Tanto), HH (Hellhound), and Bayonet. The Ultratech also comes in a custom version from the Marfione Custom Shop located inside Microtech Knives HQ.
