The Microtech Ultratech is the first ever OTF (out the front) automatic knife produced by Microtech Knives. Since 1999 there have been over 50,000 models in circulation making it an industry leader. It features a 3.4" Tanto blade with MT's apocalyptic stonewash finish and standard edge. The Ultratech features a 5" anodized 6061-T6 aluminum handle with bead blast finished pocket clip, glass breaker and stainless steel hardware. The Ultratech's spring remains at rest in both the open and closed position to help relieve fatigue on the spring compression allowing for longevity and durability.
