Microtech Dirac Delta OTF Auto Stonewash Double Full Serrate Natural Clear AUMT227D12NC

The Microtech Dirac Delta OTF Auto Stonewash Double Full Serrate Natural Clear stands as a formidable addition to the world of automatic knives, combining size, precision, and unmistakable presence. Built on the foundation of the original Dirac, the Dirac Delta expands on everything users appreciated—more length, more strength, and more capability. With an overall length of 9.4 inches, it delivers the reach and power that enthusiasts of larger knives demand, while its 3.8-inch blade ensures maximum cutting surface without compromising agility.

This model features a fully serrated double-edge dagger blade in a stonewash finish, forged from premium M390MK steel. Known for its exceptional edge retention and resistance to wear, M390MK gives the Dirac Delta the reliability you expect in situations where performance can’t falter. The serrations bite into fibrous and resistant materials with efficiency, making this knife more than just a showpiece—it’s a serious cutting tool built for work.

The Natural Clear aluminum handle provides a unique aesthetic by showcasing the internal components of the knife. Rugged and lightweight, the 6061-T6 aluminum construction keeps the weight at just 4.6 ounces, balancing the size of the blade with comfort in carry. Microtech’s precision machining ensures a smooth, contoured grip that feels solid and confident in hand, whether in a gloved grip or bare palm.

One of the defining features of the Dirac Delta is its top cover firing button. Unlike most OTF designs with a side slider, the Dirac Delta’s top-mounted switch allows for ambidextrous deployment, adding speed and comfort to its operation. With a simple push, the blade rockets forward into place, locking with Microtech’s signature authority. When retracted, the knife’s slim profile rides low and secure in the pocket thanks to its tip-down pocket clip and integrated glass breaker.

The Dirac Delta is for those who want more than just a compact everyday carry knife—it’s for users who value size, cutting power, and rugged dependability. Whether it’s a part of your EDC rotation or reserved for the outdoors, this OTF automatic proves itself with every snap of the blade. The Microtech Dirac Delta OTF Auto in Natural Clear packs a powerful 3.8" stonewash fully serrated blade into a bold, ergonomic design. Find yours today at SMKW!
