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.
