As the flagship model of Microtech’s OTF lineup, the Ultratech® sets the standard for OTF technology. Proprietary technology allows the firing spring to be at rest in both the open and closed positions, drastically reducing wear on the internal firing mechanisms. The contoured chassis handle provides a lighter and more ergonomic feel and comes in a smooth, flat finish.The Microtech Ultratech is the first ever OTF (out the front) automatic knife produced by Microtech Knives. It features a 3.4" blade with various blade finishes and styles. The Ultratech features a 5" anodized 6061-T6 aluminum smooth handle with pocket clip, glass breaker and stainless steel hardware. Dual action thumb slide for automatic deployment and retraction.
