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.

    Simply, a beautiful knife!

    The Dirac, as with all microtech knives, is of the highest quality, workmanship and materials! They are a pleasure to own, use and collect! I couldn’t be happier with EKnives! It is by far the finest knife store I’ve ever dealt with! Their service is above reproach, and they enjoy what they’re doing and have a sense of humor with the little goodies! I couldn’t be any happier getting my knives from them: they are the best!!!!

    Microtech what else needs to be said. Smooth action, solid lock up, razor edge and the face mounted trigger slide is a great option allowing a more natural grip when pulled from your pocket.

    Awesome OTF tactical knife at a great price… I love EKnives & would highly recommend them to anyone who appreciates fine edged works of art.

    Dirac Delta Shadow

    The knife is exactly what I was looking for. It is very versatile with the double edge where one side is straight and the other serrated. You can definitely feel the quality in the sliding mechanism as well. I would recommend it.
