The Microtech Dirac Delta combines the clean, modern profile of the Dirac series with a larger, more substantial format. Its distinctive design places the thumb slide on the front handle rather than along the spine, giving this OTF automatic an unmistakable look and intuitive operation.
This version features a 3.79-inch dagger blade crafted from Microtech’s proprietary Böhler M390MK premium steel with a full serrated edge and rugged Stonewash finish. The dual-action out-the-front automatic mechanism allows the blade to deploy and retract with a simple press of the thumb slide, delivering fast, dependable operation in a remarkably compact package.
Microtech developed M390MK in collaboration with engineers at Böhler to improve edge retention and corrosion resistance over the already-popular M390 platform. The tan anodized 6061-T6 aircraft-grade aluminum handles provide lightweight strength and a rugged, understated appearance that complements the Stonewash blade.
An ambidextrous stainless steel pocket clip supports versatile carry, while the integrated glass breaker adds practical utility. Measuring 4.33 inches closed and weighing just 2.37 ounces, the Dirac Delta offers an impressive balance of capability, portability, and durable construction.
Proudly made in the USA, this larger-format OTF combines premium materials, precision engineering, and distinctive Microtech styling in a compact package built for everyday carry.
