The Microtech Dirac 225-10 is a premium compact out-the-front automatic knife that introduced an entirely new ergonomic approach to Microtech's OTF lineup. As the company's first dual-action automatic to feature a top-mounted thumb slide, the Dirac delivers a uniquely natural firing motion while maintaining the precision, reliability, and premium craftsmanship that have made Microtech one of the industry's most respected manufacturers.
This exact configuration features a stonewashed double-edge dagger blade crafted from premium Böhler M390 stainless steel. Known for its exceptional edge retention, corrosion resistance, and wear resistance, M390 provides long-lasting cutting performance with minimal maintenance. The stonewashed finish helps conceal scratches from everyday use while giving the blade a clean, working appearance. The symmetrical dagger profile showcases Microtech's precision grinding and premium fit and finish.
One of the defining features of the Dirac is its face-mounted thumb slide, positioned on the front of the handle instead of along the side like most Microtech OTFs. Inspired by the legendary HALO platform, this design creates a more comfortable thumb position and contributes to the exceptionally smooth deployment and retraction that has made the Dirac series a favorite among Microtech enthusiasts.
The black aircraft-grade aluminum handle features flowing ergonomic contours that fit naturally in the hand while remaining compact enough for comfortable everyday carry. A reversible deep-carry pocket clip accommodates both right- and left-handed users, while the integrated glass breaker completes the knife's premium feature set.
Proudly manufactured in the USA, the Microtech Dirac 225-10 combines innovative ergonomics, premium materials, and Microtech's legendary dual-action OTF mechanism into one of the finest compact automatic knives available.
