Microtech Dirac OTF Automatic Knife Black D/E Red Aluminum AUMT2251RD

Built for those who demand reliability, speed, and modern design in one cohesive package, the Microtech Dirac Delta is a full-sized out-the-front automatic built to perform under pressure. It takes the innovative spirit of the original Dirac—known for its front-facing deployment switch—and scales it up, offering a more substantial feel in hand without sacrificing balance or agility.

The Dirac Delta features a 3.79" double-edged dagger blade crafted from premium steel, finished in a rugged stonewash that resists wear and keeps a low profile. Its dual-action automatic mechanism fires and retracts the blade with authority, all controlled by the front-mounted thumb slide for intuitive operation with either hand.

The anodized blue handle is milled from 6061-T6 aircraft-grade aluminum, engineered for strength without excess weight. At just 2.37 ounces and 4.33" closed, this knife is easy to carry but ready for hard use. The clean, contoured profile sits comfortably in the pocket, aided by a reversible stainless steel pocket clip and topped off with a hardened glass breaker for emergency situations.

The Dirac Delta’s hardware—like its action—is tight, responsive, and built for daily carry or tactical deployment. Every component is precision-machined in the USA, reflecting Microtech’s commitment to top-tier craftsmanship. If you want an OTF that blends sleek design with no-compromise toughness, the Dirac Delta delivers.
