Microtech Dirac Delta OTF Automatic Knife Tactical Blackout D/E 3.75" Blade. 5.5" Closed. 9.25" Overall. 4.55oz. AUMT2271T

The Microtech Dirac Delta OTF Automatic Knife Tactical Blackout D/E pushes Microtech’s innovative out-the-front design into a larger, hard-use platform built for reliability and speed. The Dirac line stands out immediately thanks to its sleek, modern styling and distinctive profile, but the most noticeable difference is the actuator placement. Instead of riding along the spine, the thumb slide is positioned on the face of the handle, giving you natural control and a comfortable, intuitive feel when deploying the blade.

The 3.75" dagger blade is crafted from premium steel and finished with a durable black coating that adds corrosion resistance while eliminating glare. The double-edge profile delivers exceptional piercing capability and balanced cutting performance, making it well suited for demanding everyday carry. Its dual-action out-the-front mechanism fires the blade forward with authority and retracts it just as smoothly with a pull of the thumb slide, delivering the crisp, dependable action Microtech is known for.

The handle is built from anodized black 6061-T6 aircraft-grade aluminum, offering impressive strength while keeping the knife lightweight and easy to carry. Its streamlined shape provides a solid, confident grip without unnecessary bulk. A stainless steel ambidextrous tip-down pocket clip keeps the knife secure and accessible for right- or left-handed users, while the integrated glass breaker adds valuable emergency functionality. Measuring 5.5" closed and weighing 4.55 ounces, the Dirac Delta delivers full-size capability in a carry-friendly design that’s ready for daily use.
