Microtech Dirac Delta Signature Series D/E
The Dirac Delta from Microtech is a full-size double-action OTF automatic from the Signature Series—built for collectors, enthusiasts, and those who want a premium automatic with serious visual presence. This USA-made knife features a 3.79-inch M390MK double-edge dagger blade with one fully serrated edge and one plain edge, finished in Bronzed Apocalyptic for a worn, battle-ready appearance. At 9.4 inches overall and 4.6 ounces, the Dirac Delta delivers a substantial presence in hand while keeping the clean, symmetrical profile that defines the Dirac family.
The double-action OTF mechanism deploys and retracts the blade through the front-mounted firing slide, giving the knife its distinctive automatic action. The aluminum handle in Sand Dune Camo pairs with the Bronzed Apocalyptic blade for high-contrast styling that stands apart from standard production configurations. The serrated edge handles rope, webbing, and tougher materials, while the plain edge provides clean, controlled slicing for finer work. M390MK steel offers excellent corrosion resistance and edge retention for demanding use. As a Signature Series release, this model emphasizes unique finishing and limited-style presentation, making it a premium choice for anyone seeking a full-size automatic with aggressive styling and unmistakable Microtech action.
