A New model called the Dirac (DER-ACK) Delta, a slightly larger version than the Dirac from Microtech Knives. The Dirac and Dirac Delta are the very first offering from Microtech Knives to feature the OTF slider on the front of the handle instead of the side. The Dirac Delta is about the size of the Combat Troodon and the Dirac is similar to the UTX-85 in size.

    Not what I expected

    Posted by Jeff Lucius on Jan 3rd 2023

    I bought the Microtech Dirac first. It is a wonderful knife: beautiful, blue with black accents, very pocket friendly, super easy to open and close with one hand, and lightweight. I wanted the Dirac Delta because I didn't have a large OTF with a serrated blade, wanted to compare it to my Infidel, and expected it to function as easily as the Dirac. Well ... it opens and closes just like the Infidel. That is, I can open both easily with one thumb, but both require my two old, partly arthritic thumbs to close. I'm sure younger folks should have no problems with either of them!

    The thing of nightmares

    This knife is incredible. Super snappy, sharp serrations, and classy looking. I started with a benchmade infidel but after some issues I swapped it for one of these and couldn’t be happier. Much snappier action, and the thing is beautifully terrifying. Can’t recommend it enough!.
