The Microtech L.U.D.T knife series is a premium automatic knife at an affordable price. This is one of those knives that is not fancy or flashy but it works...and it works well. Microtech starts with a contoured aluminum handle that has great ergonomics whether you have a larger or a smaller hand. The blade is a drop point made of M390 or 204P super steel and has a contoured spine with soft yet effective gimping on top for hard use. The blade deploys quickly and is one of the snappier automatic knives I have encountered. The custom hardware and lanyard finish it off nicely.
The Microtech LUDT series of knives can be found in a variety of color combinations and can be plain edge or partially serrated.
