Microtech LUDT Automatic Knife OD Green (3.4" Satin) 135-4OD

  • Satin-finished drop point blade made from premium steel.
  • Push button opener for one-handed automatic firing.
  • Milled OD green 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.

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.

Customer Reviews

simply amazing.
JAMES A. on Nov 13, 2019

I would call this the ideal size for a pocket knife. The blade geometry is amazing in every respect. The knife snaps open with authority, being automatic. I own two! I never do that! It's a great knife.

Crazy Sharp
Nate B. on Sep 25, 2019

First off, this knife is crazy sharp right out of the box! I mean super hair-pop'n sharp! The action is fast and solid. The ergos are decent but not the best. Build quality is great and solid. Highly recommended!

Great EDC knife!
