The Microtech Dirac Delta OTF Automatic Knife Tactical Blackout D/E is built for serious performance, combining Microtech’s distinctive design with powerful out-the-front action and rugged construction. The Dirac series stands apart with its clean, modern lines and unmistakable profile, most notably the thumb slide positioned on the front face of the handle instead of along the spine. This forward-mounted actuator provides natural thumb placement, giving you smooth, confident control over deployment and retraction.
This version features a 3.75" premium steel dagger blade with a durable black coated finish and aggressive serrations that bite deep into tough materials. The double-edge design offers excellent piercing strength while the serrated edge excels at slicing through rope, webbing, and other fibrous materials. Its dual-action out-the-front mechanism launches the blade forward with authority and pulls it back just as easily with the same thumb slide, delivering the fast, reliable automatic performance Microtech is known for.
The handles are crafted from anodized black 6061-T6 aircraft-grade aluminum, providing exceptional strength without adding unnecessary weight. The streamlined handle design fits comfortably in hand while maintaining a tough, tactical appearance that matches the blackout theme. A stainless steel ambidextrous tip-down pocket clip ensures secure carry for either hand, while the integrated glass breaker adds valuable emergency capability. Measuring 5.5" closed and weighing just 4.55 ounces, the Dirac Delta offers a full-sized automatic platform that carries easily and performs when needed.
