The Microtech Dirac Delta OTF Auto brings the proven Dirac platform into a larger, more substantial format while maintaining the quick-access functionality and refined ergonomics that define this distinctive Microtech automatic. With an overall length of 9.4 inches and a 3.8-inch blade, the Dirac Delta offers a commanding presence in hand while remaining comfortable enough for everyday carry.
The double-edge blade is crafted from premium M390MK steel and features a versatile combination edge. One side of the blade is fully serrated, while the opposite side is PlainEdge, giving you two distinct cutting surfaces in one compact package. The serrated edge is well suited for materials that benefit from aggressive sawing cuts, while the plain edge provides a smoother cutting surface for more controlled tasks. Together, they give the Dirac Delta a useful balance of cutting capabilities.
Both the blade and handle feature the distinctive Plague Outbreak Signature Series finish. This coordinated treatment gives the knife a bold, unmistakable appearance from tip to handle, making it a standout addition to any Microtech collection. The specialized finish complements the Delta's larger profile while reinforcing its rugged, purpose-driven character.
The Dirac Delta uses a top-cover firing button for automatic deployment. Positioned for straightforward access, the firing button allows the blade to deploy quickly with a natural thumb motion. The double-action OTF mechanism also allows the blade to retract with the same control, providing convenient one-handed operation when you're ready to put the knife away.
At 9.4 inches overall, the Dirac Delta is designed for users who prefer a larger OTF without sacrificing carry comfort. Its 4.6-ounce weight keeps the knife manageable while giving it a substantial feel in the hand. The enlarged dimensions provide additional handle room and a more robust presence compared with the original Dirac, making it particularly appealing to those who prefer a larger everyday carry knife.
M390MK steel provides a premium foundation for the blade, offering excellent edge retention and corrosion resistance for demanding everyday cutting. Combined with the automatic OTF mechanism and dual cutting edges, the Dirac Delta delivers a versatile setup in a highly recognizable Microtech platform.
The Microtech Dirac Delta Plague Outbreak Signature Series combines a larger ergonomic design, M390MK steel, double-edge versatility, and coordinated Signature Series finishes. With a fully serrated edge on one side and a plain edge on the other, it's equipped to tackle a broad range of cutting tasks while making a bold statement in any collection.
