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 bead blasted Elmax steel blade and black 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.

Razor Sharp
James H.
One of my best autos with powerful release and lockup....this is by far the SHARPEST blade I have ever received in the mail.....dangerously sharp, like a straight razor.....well worth the money for a superb quality knife.....feels great in my large hands......
Biggish Blade, Huge Value
Philip E.
This knife, at first, holds that Plain Jane kind of essence. As I looked at it more, though, I began to realize how beautiful it is. Its wonderful lines in the blade, its precise, symmetrical handle milling, its cutouts on the top of the handle, and the way the handle tapers. All contribute to a great aesthetic.

The only miss, for me, is the jimping on the upper portion of the spine of the blade. It serves no function, and holds little form. I would hope that instead, the thumb ramp would have nice, sharp jimping.

It's not a big deal, honestly. I hardly notice it, as it isn't used.

Size, weight, ease of carry:
It's about a mid-size knife, and comes with a fairly big blade. All the size is in its height, rather than its length. For a knife this size, the weight is pretty impressive.
The fantastic pocket clip lends to a very easy carry, and deployment.

Materials, durability:
Handle material is 6061-T6 aluminum, and this model's blade is Elmax.
Just wonderful.
I haven't taken to beating my knife around, but I'm sure it will have excellent longevity.

Speed is okay. The big blade is fired by a robust coil, using a large and unmistakable button. Button depression can be a bit hard, out of box. The exposed pivot, surprisingly, does not distract from the button. This is due mostly to Microtech's proprietary fastener head.
Anyway, the point is that the blade is a bit big to expect lightning speed, but there is nothing wrong with how it deploys.
Lockup is superb.

Price/competitive options:
At $200, you have a lot of options in the knife world. Would you like Benchmade's 477-1? How about Wilson Combat's ELC? A ProTech TR3, maybe?
If it's only an automatic knife you're after, I say look no further. This knife is fantastic.

Bottom line: It's a Microtech. This is a heavy hitter as far as value. It's not hard to find $200 knives, but this one will definitely stay in my collection.
