The Dirac is the first Microtech double action knife with a cover firing slider. The extremely ergonomic chassis features curved lines similar to the HALO for a slightly different feel, compared to other handles. They researched this particular OTF design and applied their signature ultra-high tolerance Microtech features such as proprietary hardware, innovative internal mechanism, and glass breaker. With an overall length of 9.4 inches, the Dirac is just right for an everyday or tactical knife.
