The Microtech Ultratech is the first ever OTF (out the front) automatic knife produced by Microtech Knives. The dual action automatic that started it all is the smoothest operating out the front you will find. It features a 3.4″ blade. The Ultratech has a 5″ 6061-T6 aluminum handle with bead blast finished pocket clip, glass breaker and stainless steel hardware. The double action slide switch allows for fast automatic deployment and retraction when you need it. The slim design of the Ultra make it the perfect EDC knife.
