The LUDT is a larger version of the Underwater Demolition Team of automatic knives that have evolved to be an exceptional combination of form and function. The first prototype models featured rubber Kraton™ inlays and were available in small, medium, and large sizes. These models were later consolidated to a single size, featuring a grooved, contoured aluminum handle with jimping along the top of the handle that carries onto the spine of the blade. The L.U.D.T.® boasts an explosive deployment mechanism not commonly found in a knife of this size 3.4 inch blade is perfect for EDC use. The L.U.D.T.® has rising sales among campers for its lightweight design and ease of use, which make it a great EDC knife for outdoorsmen and of course, underwater demolition teams. All hardware is stainless steel including pocket clip.
