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 an intuitive method of operation.
This version features a 3.79-inch dagger blade crafted from Microtech’s proprietary Böhler M390MK premium steel and finished with a black coating for a sleek, tactical appearance. 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.
Microtech developed M390MK in collaboration with engineers at Böhler to improve edge retention and corrosion resistance over the already-popular M390 platform. The cyan anodized 6061-T6 aircraft-grade aluminum handles add a vivid splash of color while providing lightweight strength and durability.
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 rugged construction.
Proudly made in the USA, this larger-format OTF brings together premium materials, precision engineering, and distinctive Microtech styling in a compact package that’s built to perform.
