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 platforms, refined with modern engineering upgrades and premium materials for dependable, hard-use performance. Known for its straightforward design, rock-solid reliability, and consistent operation, the L.U.D.T. remains a proven automatic built for everyday carry and demanding environments alike.
Its 3.5" partially serrated tanto blade is crafted from Microtech’s proprietary Böhler M390MK stainless steel, delivering a balance of strength, edge retention, and corrosion resistance built for real-world use. The tanto profile reinforces the tip for added durability during piercing and utility tasks, while the partially serrated edge adds aggressive cutting performance for rope, cord, and fibrous materials. Developed in collaboration with Böhler engineers, M390MK refines the already elite M390 steel, improving edge retention and long-term toughness under heavy use conditions.
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 operation, while Krud Kutter grooves 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 constructed from Merlot anodized 6061-T6 aircraft-grade aluminum, offering lightweight strength with a rich, deep wine-red finish. The anodized coating enhances corrosion resistance while maintaining structural integrity through heavy use. Satin finished hardware provides a clean contrast, while the stainless steel pocket clip and lanyard hole with black paracord lanyard add versatile carry options. Measuring 4.5" closed and weighing 3.6 ounces, it delivers compact portability without sacrificing capability. Proudly made in the USA, it reflects Microtech’s continued commitment to precision engineering and dependable performance.
