Microtech Dirac Delta OTF Automatic Knife Partially Serrated Black D/E Olive Drab Green AUMT2272OD

The Microtech Dirac Delta OTF Automatic Knife with partially serrated black-coated dagger blade brings serious heft and tactical edge to the lineup—larger scale for bigger tasks while keeping that lightning-fast Microtech snap. The 3.79-inch dagger blade, forged from elite M390 stainless steel and finished in a tough black coating, merges clean plain-edge slicing with partial serrations that tear through rope, webbing, or heavy cordage like it's nothing. It deploys and locks with explosive dual-action speed via the front thumb slide—smooth, instinctive, and built to perform under pressure.

The olive drab green anodized 6061-T6 aircraft-grade aluminum handles deliver a low-key, battle-ready grip—subtle military vibe that locks in tight through sweat, mud, rain, or gloves without a slip. It carries surprisingly light for its size on the ambidextrous stainless steel clip, with the integrated glass breaker always primed to punch through glass or barriers when seconds count.

Handcrafted in the USA by Microtech, the Dirac Delta combines enlarged precision engineering with no-nonsense toughness and stealthy styling—crafted for rapid draws, hard-hitting daily carry, and those who gear up for real-world demands.
