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.

    My favorite...

    Posted by James McNeese on Aug 7th 2025

    I have 4 Microtech knives 2 makora ll and a ultratech Hellhound Razor. My resent buy was a Dirac Delta D/E tactical. This knife fits my hand very well and the button on the face makes it much easer to deploy. The knife is made very well as all Microtech knifes are, and the blade looks bad a- - , and very sharp. This is my FAVORITE as of now. You can't go wrong with any purchase of a Microtech knife. Thank you E Knives and Coco for all your help and fast shipping.

    I love this knife. It works flawlessly and looks great while doing so. There’s just something so satisfying about the blade flying out, the slight recoil you feel just makes life worth living

    I’ve been a Benchmade advocate for as long as I can remember. From the Infidel to the shootout. I purchased my first Microtech from EKnives (Dirac Delta) and have made the switch to these being my all time favorite blades. I purchased the black two tone dagger and it’s amazing, has so much “snap” to the opening and closing, wouldn’t call it “recoil” but if a knife had that feel this is it. After receiving it I ended up getting the Dirac Delta Apocalyptic blade as well. Stoked to receive that one too! I’m waiting for the Bronze to come back and I’ll have to add that one to the collection as well. Big thanks to EKnives! Fast shipping, keeps you up to date on the status, and sends you a band aid and some sweet tarts! Amazing company. Will be making all my purchases from EKnives from this point forward. Thanks again EKnives!

    I bought the item on a Sunday night and it was shipped on a Monday morning to get delivered to me within the same week. Fast delivery and the Dirac Delta I got has a perfect edge out of the box. The knife itself is also just an amazing OTF with a great action and feel.

    Big blade

    Posted by Josh on Feb 4th 2023

    It looks very cool, and the blade is pretty easy to retract.
