Microtech Dirac Delta Out-the-Front Automatic Knife Dual Serrated Stonewash D/E Natural Clear Aluminum AUMT22711NC

The Microtech Dirac Delta out-the-front automatic brings a bold, modern profile to the OTF world while keeping every ounce of the precision and reliability the brand is known for. Engineered for confident, one-handed operation, the Delta takes the original Dirac’s innovative design—placing the slide on the front of the handle for improved ergonomics—and scales it up for a larger, more commanding presence in hand.

Its 3.79" dual-serrated dagger blade is crafted from premium steel, chosen for superior edge retention and strength under demanding conditions. A rugged stonewash finish adds a layer of scratch-hiding durability while giving the blade a work-ready appearance. This dual-action automatic deploys and retracts with a swift push or pull of the front-mounted thumb slide, locking up securely for immediate use.

The gray aircraft-grade aluminum handle provides a strong yet lightweight frame, with clean machining that offers both comfort and grip without unnecessary bulk. Stainless steel hardware, an ambidextrous pocket clip, and an integrated glass breaker round out its mission-ready build. At 4.33" closed and weighing just 2.37 oz, the Dirac Delta balances a full-size feel with carry-friendly proportions.

Proudly made in the USA, it’s a knife built for those who expect flawless action, solid construction, and a look that’s both tactical and refined. Whether carried for professional duty or personal readiness, the Dirac Delta stands as a formidable tool with uncompromising quality.
