Microtech Ultratech Gen IV OTF Automatic Knife Partially Serrated Stonewash D/E Brown AUMT1122411BN

The Microtech Ultratech Gen IV stands as the latest refinement of one of the most influential out-the-front automatics ever produced. Built on a legacy of precision engineering and battlefield-proven reliability, the Ultratech remains Microtech’s signature OTF platform, and the Gen IV update pushes it forward with improved internal mechanics, smoother operation, and enhanced durability for everyday and hard-use performance.

This configuration features a 3.55" partially serrated dagger blade crafted from Microtech’s proprietary Böhler M390MK premium stainless steel, finished in a rugged stonewash. The finish helps conceal wear from heavy use while delivering a clean, functional appearance suited for demanding environments. The dagger profile provides aggressive, symmetrical piercing capability, while the partially serrated edge adds cutting strength for rope, cord, and tough fibrous materials. M390MK is developed in collaboration with Böhler engineers to elevate the already elite M390 formula, improving edge retention, corrosion resistance, and long-term toughness.

The Gen IV Ultratech incorporates Microtech’s Dual-Fuel Drive Train, engineered to deliver smoother, more consistent blade deployment and retraction through the thumb slide. It enhances the classic dual-action OTF system with improved feel and control, while the integrated Crud Kutter system helps clear debris from the internal mechanism to maintain reliable performance in harsh conditions. The upgraded glass breaker adds dependable emergency utility without compromising carry comfort.

The handle is crafted from brown anodized aircraft-grade aluminum, offering a warm, earth-toned aesthetic paired with lightweight strength and excellent durability. Its ergonomic shape ensures a secure, confident grip, while the ambidextrous stainless steel Signature Series pocket clip allows versatile carry options. A lanyard hole adds additional retention capability for field use. Measuring 4.99" closed and weighing just 3.61 ounces, it delivers full-size OTF performance in a slim, carry-friendly package. Proudly made in the USA, it reflects Microtech’s continued pursuit of precision and innovation.
