The Ultratech double action out-the-front automatic from Microtech sets the standard for the category. With a sleek durable design, precision American made construction and premium materials, the Ultratech is a perfect everyday carry companion. This version has a stonewashed M390 Tanto blade and blue aluminum handle.

Brand new, direct from Microtech Knives.

Blade: The M390 Tanto blade has a clean slicing plain edge with a rugged, wear hiding stonewashed finish on the grinds. A high saber grind provides solid slicing performance with a strong, piercing tip that is ideal for flat surface cutting. Action is fast and smooth thanks to the double action automatic mechanism. Move the thumb slide up to deploy and down to retract. An internal spring remains at rest in both the open and closed position to reduce wear.

Handle: A smooth, hard anodized 6061-T6 aluminum handle comes contoured for comfort and smooth pocket transitions. Strategic grooves around the sides improve traction for a secure grip during use. Microtech's proprietary hardware, glass breaker end and pocket clip complete the construction.

Carries via a stainless steel pocket clip.

Bohler M390: Bohler M390 (analog to CPM-20CV and CTS-204P) is a premium powder metallurgy (PM) stainless steel with high level edge retention and corrosion resistance. A popular choice for high-end production and custom knives, M390 is relatively easy to sharpen, with toughness on par with 440C/154CM.
