Microtech Dirac Delta D/E Black Blade Red Aluminum AUMT2271RD

The Microtech Dirac Delta D/E Black Blade Red Aluminum is a full-size out-the-front automatic that’s built to stand out just as much as it’s built to perform. It takes the proven Dirac platform and scales it up into a more commanding tool, delivering increased reach, enhanced control, and the same precision engineering Microtech is known for.

The 3.79-inch premium steel dagger blade is the centerpiece, finished in a durable black coating that reduces glare and adds a layer of protection against wear. The double-edge design offers symmetrical cutting performance, making it equally effective from either side while maintaining a sharp, penetrating tip. It’s a blade that’s made for decisive action, whether you’re handling everyday tasks or pushing it into more demanding use.

Like the rest of the Dirac family, the Delta features Microtech’s distinctive front-mounted thumb slide. This forward-positioned actuator gives you a more natural grip and improved ergonomics during deployment. With a firm push, the blade fires out with authority and locks into place, and with a pull, it retracts just as smoothly. The dual action mechanism is fast, reliable, and designed for consistent one-handed operation.

The handle is crafted from red aluminum, offering a strong yet lightweight frame that keeps the overall weight at 4.6 ounces. The bold red finish isn’t just for looks—it provides excellent visibility and a confident grip in hand. Clean lines and precise machining give it a solid, balanced feel, while the black tip-down pocket clip ensures secure carry and quick access. An integrated glass breaker rounds out the design, adding a practical emergency feature that makes this more than just a cutting tool.

At 5.61 inches closed and 9.4 inches overall, the Dirac Delta strikes a balance between size and portability. It’s large enough to handle serious work, yet still slim enough to carry comfortably on a daily basis. Every detail reflects Microtech’s dedication to quality, from the smooth action to the tight tolerances and durable materials.

This is a knife that doesn’t blend in—and it’s not meant to. The Dirac Delta is built for those who want bold design backed by real performance, ready to deploy at a moment’s notice.
