Microtech LUDT Automatic Knife Tan (3.4" Apocalyptic) 135-10APTA

  • Bead blasted and stonewashed drop point blade made from premium steel.
  • Push button opener for one-handed automatic firing.
  • Milled brown anodized aluminum handle.
  • Secure button lock.
  • Tip-up pocket clip and a lanyard loop.


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 an Apocalyptic finished blade and a tan anodized handle with bead blast finished 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.

My new favorite knife
Christian A. on Jul 18, 2021

I have been looking for the Microtech LUDT for almost two years. Every time I searched different websites, it was always out of stock. Then one day I saw this LUDT with apocalyptic tan handle here on Blade HQ and I thought it was a mistake. In fact, after I ordered it, the listing changed to out of stock. For a few days, while I waited for the shipping information, I wasn't sure if I really got the last one or if it was a mistake and they never had the knife... and then I received it and WOW! The knife is smaller than I expected, comparable in size with my ZT 0357 and slightly smaller than my Spyderco Paramilitary 2. The best way to describe the automatic mechanism is "violent". You push the button and the blade just snaps out in a blink of an eye. And the blade is SHARP. Mine came with the Carpenter CTS 204P steel and it is SHARP. I am very happy that the knife came with American steel and it looks fantastic. The aluminum handle is very comfortable - more than I thought it would be, and it comes with a nice lanyard as a bonus. I am VERY happy with this purchase. I've been searching for this knife for a long time and it did not disappoint! 5 stars!
