As the pioneer of Microtech's folding knife line, the U.D.T. has 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 jibbing 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.
