Microtech Dirac Delta OTF Automatic Knife Plain Edge Stonewash D/E Navy Blue AUMT22710NA

The Microtech Dirac Delta takes everything that made the original Dirac a standout and scales it up for those who prefer a knife with greater presence and cutting authority. Its clean, modern lines are paired with Microtech’s distinctive front-mounted thumb slide, a design that promotes a more natural hand position while allowing swift, controlled deployment. Built with precision and purpose, this is an automatic that feels every bit as powerful as it looks.

At the center of the Dirac Delta is a commanding 3.79" dagger blade crafted from premium M390 stainless steel. Known for exceptional edge retention, strength, and corrosion resistance, this steel is trusted by serious knife users who expect consistent performance. The rugged stonewash finish adds a hard-use character while helping conceal the marks that come with demanding tasks. Whether it’s part of your everyday carry rotation or reserved for situations that call for absolute reliability, this blade is ready to answer.

The dual-action out-the-front mechanism operates with smooth, decisive force—push the thumb slide forward to deploy the blade and pull it back to retract. Each movement feels deliberate and secure, reinforcing the confidence that comes from Microtech’s meticulous engineering.

The anodized Navy Blue handle is machined from aircraft-grade aluminum, delivering an ideal balance of durability and manageable weight. It offers a solid, comfortable grip without unnecessary bulk, while the ambidextrous stainless steel pocket clip supports convenient carry for right- and left-handed users alike. An integrated glass breaker adds a practical emergency feature, rounding out a knife designed for preparedness.

Measuring 5.61" closed and weighing 4.6 ounces, the Dirac Delta provides substantial capability while remaining comfortable to carry. Proudly made in the USA, it stands as a testament to Microtech’s commitment to quality craftsmanship.
