Microtech Dirac Delta OTF Automatic Knife Partially Serrated Black D/E Orange AUMT2272OR

The Microtech Dirac Delta OTF Automatic Knife with partially serrated black-coated dagger blade packs serious authority in a larger frame—delivering that same blistering speed with added reach for demanding tasks. The 3.79-inch dagger blade, forged from elite M390 stainless steel and wrapped in a durable black coating, fuses precise plain-edge cutting with partial serrations that chew through rope, webbing, or rugged material on demand. It explodes open and locks tight via the front thumb slide—dual-action deployment that's instinctive, fast, and built for high-stakes moments.

The anodized 6061-T6 aircraft-grade aluminum handles in vibrant orange bring bold, high-visibility energy while clamping down with a confident, no-slip grip—holding firm through sweat, rain, mud, or gloves without hesitation. It carries deceptively light for its size on the ambidextrous stainless steel clip, with the integrated glass breaker ready to smash through glass or barriers the instant you need it.

Handcrafted in the USA by Microtech, the Dirac Delta unites scaled-up precision engineering with tactical toughness and standout styling—crafted for rapid draws, heavy-duty carry, and those who gear up knowing the job won't wait.
