Microtech Dirac Delta Out-the-Front Automatic Knife Satin Dagger/Black AUMT2274

The Microtech Dirac Delta brings refined aggression to the table with a larger footprint, clean lines, and rock-solid automatic performance. This version is outfitted with a 3.79" dagger blade in a plain edge configuration, made from premium stainless steel with a flawless satin finish. It's a dual-action out-the-front automatic, engaging and retracting with a crisp, confident snap using the front-mounted thumb slide—a design that offers smooth ambidextrous operation and a streamlined profile.

The handle is crafted from 6061-T6 aircraft-grade aluminum, anodized in a matte black that complements the satin blade for a sleek, low-profile aesthetic. Its ergonomics are precise, providing a secure grip in both forward and reverse positions. The Dirac Delta’s symmetrical design makes it especially comfortable for gloved or tactical use, while the precision machining ensures durability under demanding conditions. Microtech’s proprietary hardware, a hardened glass breaker, and a reversible stainless steel pocket clip round out the features, making this knife as functional as it is formidable.

With the Dirac Delta, Microtech has taken their clean, modern OTF concept and scaled it for users who want more reach without added bulk. Whether you’re a first responder, collector, or enthusiast, this knife is engineered for fast deployment, serious cutting ability, and rock-solid reliability in a compact, carry-friendly package.

Closed, it measures 4.33" and weighs just 2.37 ounces. Like every Microtech, it's proudly made in the USA with elite materials and craftsmanship you can count on.
