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.

    Awesome tool for people with large hands. The Dirac original is too small for mine.

    The Dirac Delta is one of my favorites from Microtech. Received my order in 3 days from time placed. Coco was helpful and friendly. I’ve purchased knives from Clay at EKnives for years. Never had any type of issue whatsoever. Highly recommend.
