Microtech Dirac Delta OTF Automatic Knife Serrated Black Dagger/OD Green AUMT2253OD

Built for those who demand performance and presence in equal measure, the Microtech Dirac Delta delivers bold out-the-front action in a larger, more substantial package. This Delta model features a 3.79" fully serrated dagger blade with a tough black coated finish and premium steel construction. It’s designed for reliable penetration, fast slicing, and confident utility. The blade fires and retracts with Microtech’s signature dual-action thumb slide, mounted cleanly on the front of the handle for intuitive, ambidextrous operation.

The Dirac Delta stands apart with a sleek yet tactical profile, built around a solid chassis of 6061-T6 aircraft-grade aluminum. The handles are anodized in a deep olive drab green that pairs well with the black hardware and blade, giving the knife a serious, mission-ready appearance. The slim, symmetrical frame houses tight tolerances and excellent machining, delivering a high-end feel in hand. It’s finished with Microtech’s signature hardware, a glass breaker for emergency situations, and a reversible stainless steel pocket clip for carry on either side.

This knife doesn't just look sharp—it performs with authority. Whether you're on duty or off-grid, the Dirac Delta is built to handle the unexpected with precision and speed. It offers everything users appreciate about Microtech’s automatic lineup, but scaled up for those who prefer more blade length and a bit more grip without sacrificing pocketability.

The Dirac Delta is 4.33" closed, weighs 2.37 ounces, and is proudly made in the USA with a fit and finish worthy of the Microtech name.
