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.
