The Microtech L.U.D.T. (Large Underwater Demolition Team) Gen III automatic knife carries forward one of Microtech’s most trusted side-opening platforms, refined with modern engineering upgrades and premium materials for consistent, hard-use performance. Known for its straightforward operation, rugged durability, and dependable deployment, 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 exceptional edge retention, corrosion resistance, and long-term toughness in real-world conditions. The tanto profile reinforces the tip for added strength during piercing and controlled utility tasks, while the partially serrated edge adds aggressive cutting capability for rope, cord, and fibrous materials. Developed in collaboration with Böhler engineers, M390MK refines the already elite M390 steel to push performance even further under heavy use.
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 olive drab green anodized 6061-T6 aircraft-grade aluminum, offering lightweight strength with a classic field-ready aesthetic. The anodized finish enhances corrosion resistance while maintaining structural integrity through demanding use. Satin finished hardware adds a clean contrast, while the stainless steel pocket clip and lanyard hole with black paracord lanyard provide 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.
