Microtech Ultratech Gen IV OTF Automatic Knife Blackout Partially Serrated S/E AUMT112142T

The Microtech Ultratech Gen IV carries forward the legacy of one of the most respected out-the-front automatics ever built, refined through decades of real-world performance and continuous engineering upgrades. As Microtech’s flagship OTF, the Ultratech has become the benchmark for speed, reliability, and precision, and the Gen IV iteration elevates that standard with improved internal mechanics and enhanced durability throughout.

This version features a 3.55" partially serrated drop point blade crafted from Microtech’s proprietary Böhler M390MK premium stainless steel, finished in a deep black DLC (diamond-like carbon) coating. The DLC finish adds extreme surface hardness, increased wear resistance, and a low-reflective tactical appearance built for hard use. M390MK itself is developed in collaboration with Böhler engineers to refine the already elite M390 steel, delivering improved edge retention, excellent corrosion resistance, and long-term toughness in demanding environments. The partially serrated edge adds cutting power for rope, cordage, and abrasive materials, while the drop point profile keeps the blade versatile and controlled.

The Gen IV Ultratech introduces Microtech’s Dual-Fuel Drive Train, designed to deliver smoother, more consistent deployment and retraction through the thumb slide. It refines the classic dual-action OTF system for improved feel and reliability under repeated operation. The integrated Crud Kutter system helps clear debris from the internal mechanism, supporting consistent performance in harsh or dirty conditions, while the upgraded glass breaker enhances emergency functionality.

Black aluminum handles complete the tactical aesthetic with a lightweight yet durable construction that stands up to daily carry and demanding use. The natural ergonomic profile provides a secure grip, while the ambidextrous stainless steel Signature Series pocket clip ensures versatile carry options. A lanyard hole adds additional attachment flexibility. At 4.99" closed and 3.61 ounces, it delivers full-size capability without excess weight. Proudly made in the USA, it reflects Microtech’s relentless pursuit of precision and performance.
