Microtech Dirac Delta D-E Standard Outbreak Signature Series 3.78In. Dagger OTF Automatic AUMT2271OBDS

The Microtech Dirac Delta D/E Standard Outbreak Signature Series is a high-performance OTF automatic built for demanding users who want precision, reliability, and unmistakable visual impact. With a rugged design and bold aesthetics, this full-size automatic knife combines Microtech’s top-tier engineering with a striking distressed “Outbreak” finish, setting it apart from conventional tactical folders.

Measuring approximately 9.40 inches overall, the Dirac Delta features a 3.78-inch double-edge dagger blade crafted from premium Böhler M390 stainless steel. This high-performance steel is known for its excellent edge retention, corrosion resistance, and toughness—making it ideal for field use or heavy-duty everyday carry. The plain-edge blade is flat-ground for efficient slicing and puncturing performance and finished with a battle-worn “Outbreak” treatment that extends across both the blade and handle.

The handle is constructed from deep-engraved 6061‑T6 aluminum, treated with the same distressed finish to maintain the knife’s aggressive look and tactical feel. At 5.60 inches closed and about 0.44 inches thick, the handle offers a comfortable, secure grip and houses Microtech’s precision-built, thumb-slide operated, double-action OTF mechanism. This ambidextrous deployment system ensures fast, reliable blade actuation every time.

Weighing just 4.6 ounces, the Dirac Delta maintains a lightweight profile without sacrificing strength or control. The stainless steel pocket clip is tip-down configured and reversible for both right- and left-hand carry, while the integrated glass breaker at the base of the handle adds utility in emergencies. Microtech’s ultra-tight manufacturing tolerances and quality materials make this a dependable cutting tool with real-world application, whether it’s in a duty role or a collector’s display.

Made in the USA as part of Microtech’s exclusive Signature Series, the Dirac Delta Outbreak variant is built with the same exacting standards as its military and law enforcement counterparts. This model stands out for its functionality, craftsmanship, and its gritty, battle-ready visual style. Check out our large selection of Microtech and upgrade your collection today!
