Microtech Ultratech Gen IV OTF Automatic Knife Stonewash Partially Serrated S/E Tan AUMT1121411TA

The Microtech Ultratech Gen IV continues the evolution of one of the most influential out-the-front automatics ever produced. Microtech set the standard for modern OTF performance, and the Ultratech remains the flagship platform that defines reliability, speed, and precision in its class. With the Gen IV upgrade, the design is refined further with improved internal systems, enhanced durability, and smoother, more controlled operation.

At the core of this version is a 3.55" partially serrated drop point blade crafted from Microtech’s proprietary Böhler M390MK premium stainless steel. Finished in a rugged stonewash, the blade is built to work hard while resisting wear and hiding scratches from heavy use. M390MK is developed in collaboration with Böhler engineers to improve upon the already elite M390 formula, delivering increased edge retention, excellent corrosion resistance, and long-term toughness that stands up to demanding conditions. The partially serrated edge adds extra versatility for cutting rope, fibrous materials, and everyday utility tasks, while the drop point profile maintains excellent control and all-purpose functionality.

The Gen IV Ultratech introduces Microtech’s Dual-Fuel Drive Train, engineered to deliver smoother, more consistent blade deployment and retraction through the thumb slide. It refines the signature dual-action OTF system for improved feel and reliability under repeated use. The integrated Crud Kutter system helps clear debris from the mechanism, maintaining performance in dirty or harsh environments, while the upgraded glass breaker enhances emergency capability without adding unnecessary bulk.

The handle is crafted from natural clear aircraft-grade aluminum, finished with a protective colorless anodic coating that preserves the metal’s raw industrial appearance while improving corrosion resistance and durability. It’s equipped with an ambidextrous stainless steel Signature Series pocket clip, a lanyard hole, and an upgraded glass breaker for added utility. Measuring 4.99" closed and weighing just 3.61 ounces, it delivers full-size capability in a lightweight, carry-friendly package. Proudly made in the USA, it reflects Microtech’s continued commitment to precision manufacturing.
