Microtech LUDT Automatic Knife Blue (3.4" Stonewash) 135-10BL


  • Stonewash-finished drop point blade made from premium steel.
  • Push button opener for one-handed automatic firing.
  • Milled blue 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 a stonewashed CTS-204P steel blade and blue 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.

Love after first time pushing the button
Gary K. on Nov 17, 2017

This is my first microtech and my first auto I just got mail out the mail last night. It surprised me how well centered no blade play. In the specs said it's an elmax steel knife but mine is an m390 steel knife. It's nicer in person than pics they got showing. Packs very well don't know you got in your pocket

I have owned 3 Ultratechs, a scarab, and a troodon, and this is my favorite knife between them all and for under $200. This will be my edc knife, locks up very solid and is razor sharp. Plus the blue anodizing is gorgeous, couldnt be happier
