Microtech LUDT Gen III Automatic Knife Purple Aurora S/E AUMT11351PUAUSZ4

The Microtech L.U.D.T. (Large Underwater Demolition Team) Gen III automatic knife continues the evolution of one of Microtech’s most trusted side-opening designs, refined for modern performance with upgraded engineering and premium materials. Built for consistent reliability and everyday practicality, the L.U.D.T. delivers the kind of rugged, no-nonsense operation that has made it a staple among serious users.

Its 3.5" drop point blade is crafted from Microtech’s proprietary Böhler M390MK stainless steel and finished in a striking Purple Aurora treatment. The Purple Aurora finish shifts through a vibrant gradient of purple and pink tones, giving the blade a bold, eye-catching presence while maintaining a durable surface suited for real-world use. M390MK is developed in collaboration with Böhler engineers to refine the already elite M390 steel, improving edge retention, corrosion resistance, and long-term toughness. The drop point profile offers balanced control for slicing and piercing tasks, making it a versatile everyday performer.

The Gen III L.U.D.T. features a refined push-button side-opening automatic mechanism that delivers fast, confident blade deployment with secure lockup. The upgraded Dual Fuel Drive system ensures smooth, consistent action, while Krud Kutter grooves on the mechanism help reduce pocket lint buildup for improved long-term reliability. Upgraded Torx hardware enhances durability and serviceability, and the ceramic thumb ball on the pocket clip reduces wear for extended carry life.

The handle is crafted from Purple Aurora anodized 6061-T6 aircraft-grade aluminum, matching the blade with a vivid gradient finish that shifts between rich purple and pink tones. The anodized coating enhances corrosion resistance while maintaining lightweight strength and structural integrity. Satin finished hardware provides subtle contrast, while the stainless steel pocket clip and lanyard hole with black paracord lanyard add versatile carry options. At 4.5" closed and 3.6 ounces, it offers compact portability with full-size capability. Proudly made in the USA, it reflects Microtech’s commitment to precision engineering and performance-driven design.
