The Microtech LUDT is back and better than ever! Notable changes to the LUDT automatic knife can be seen throughout, but the most prominent difference is the revised blade profile, with a notched thumb ramp and smooth crowned spine. New-school Tri-Angle hardware and a slick recessed pivot assembly add a fine touch, along with the addition of a hole for lanyard attachment.

Throwback style is seen in the milled grooves of the tapered 6061-T6 aluminum handle, which dates back to the early-2000 era models. The LUDT is what we deem "affordable excellence." It combines precision manufacturing, premium materials, and a timeless design.

This model has a partially serrated, black finished Elmax steel blade and black anodized handle with tactical black hardware.

A little over 20 years ago Anthony Marfione introduced the U.D.T. (Underwater Demolition Team), a compact automatic folder that was an instant hit among knife enthusiasts. The Large UDT, or LUDT, followed shortly thereafter and has been around intermittently ever since.

Great tactical blade!
Outstanding product

This LUDT (Black Serr) 135-2T is my favorite of many owned. The matte finish, including on all heads, makes for a true tactical knife. The revised blade profile, with notched thumb ramp, smooth crowned spine with black matte finished blade, is outstanding... exactly what you want. The action is very nice, and the overall look of this knife is perfect.

My only gripe is not about the knife, but that Microtech does not provide spec info on the size of the tri-angle heads used, in particular the heads which attach the clip. Good luck finding the correct socket for adjustments.
Great value Auto

The fit and finish is immaculate. The blade/handle ergonomics are much more attractive in person. This is an EDC you can appreciate carrying and enjoy using. It offers Microtech quality and unique hardware in a practical package at a practical price.
