Microtech Ultratech OTF Automatic Zero Blade Play DLC Standard/OD Green AUMT11211OD

The Microtech Ultratech delivers uncompromising performance in a lightweight, battle-ready build that’s trusted by professionals across the world. At the heart of this out-the-front automatic is a 3.35" drop point blade with a tough, low-profile black DLC (diamond-like carbon) coating that shrugs off wear and resists corrosion in the harshest conditions. It deploys and retracts with speed and authority via Microtech’s signature dual-action thumb slide, giving you instant access to a razor-sharp edge when it matters most.

What sets the Ultratech apart is Microtech’s patented Zero Blade Play system—an internal innovation that locks the blade in place without a hint of wobble, side-to-side or up-and-down. Once open, the blade sits with rock-solid stability, offering surgical precision and unmatched confidence during use. It’s a feature few OTFs can match, and it’s a testament to Microtech’s relentless pursuit of perfection.

The OD Green anodized 6061-T6 aluminum handle provides a rugged, military-inspired look with lightweight strength and a reliable grip. At 5.01" closed and just 3.5oz, the Ultratech carries easily without sacrificing capability. Designed, built, and assembled in the USA, every detail of this knife reflects Microtech’s high standards—from the internal mechanics to the flawless fit and finish.
