The Microtech Ultratech is the first ever OTF (out the front) automatic knife produced by Microtech Knives and is the foundation for all Microtech automatic OTF knives. The Ultratech has been through various modifications over the years but remains a top seller for Microtech.

The Microtech Ultratech automatic knife features a 5″ black anodized 6061-T6 aluminum handle with bead blast finished pocket clip, glass breaker and stainless steel hardware. The Ultratech has a bayonet double edged blade measuring 3.4″ long. This dual action automatic fires via thumb slide on the side of the handle for quick one handed deployment and retraction
