The Dirac® is our first dual action knife with a cover firing slider. We designed an updated ergonomic chassis with curved lines similar to the HALO® for a slightly different feel compared to our other handles. We researched this particular OTF design and applied our signature ultra-high tolerance Microtech® features such as proprietary hardware, innovative internal mechanism, and glass breaker. With an overall length of 7.25 inches, the Dirac® is just right for an everyday knife.
