As the flagship model of Microtech’s OTF lineup, the Ultratech® sets the standard for OTF technology.

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.
