Microtech Dirac Delta D-E Standard Weather Blue OTF Automatic 3.75In. AUMT2271WBL

The Microtech Dirac Delta D/E in Weathered Blue is a full-sized, double-action OTF automatic that brings power and precision to the everyday carry world. Inspired by the original Dirac, the Delta model expands the platform with a more substantial handle and longer blade while preserving the lightning-fast deployment and slim, ergonomic form factor users have come to expect. Its aggressive double-edged dagger blade is crafted from premium Bohler M390 steel, offering excellent edge retention, corrosion resistance, and high hardness—ideal for both defensive use and precision cutting tasks.

At 3.75 inches in length, the black-finished blade features symmetrical grind geometry and piercing capability from both edges, making it versatile and dependable. The flat grind ensures a razor-sharp edge while maintaining durability through repeated use. A front-mounted thumb slider provides seamless double-action performance, firing and retracting the blade with clean authority. The internal mechanism is engineered to Microtech’s ultra-tight tolerances, guaranteeing reliable function and long-term resilience.

The 6061 T6 aluminum handle, anodized in a rugged weathered blue finish, balances comfort and strength. Its subtly curved profile fits naturally in hand, with textural milling and jimping for enhanced grip under pressure. Blasted hardware throughout adds to the knife’s industrial look and feel, while the integrated glass breaker ensures you’re prepared for the unexpected.

Weighing just over 4 ounces, the Dirac Delta manages to feel substantial without being bulky. Its deep-carry pocket clip, also finished in blasted steel, rides tip-down for easy right-handed access and a discreet pocket profile. Whether it’s for daily cutting tasks, emergency applications, or collection appeal, this OTF stands out as a fusion of tactical readiness and refined craftsmanship.

Proudly made in the USA, the Microtech Dirac Delta D/E Weathered Blue continues the brand’s legacy of high-performance tools built to endure hard use in the field, at work, or on the move. Visit SMKW to browse and find your Microtech today!
