Dual-Action Automation and Micro-Precision Advantage
Microtech OTF knives represent the pinnacle of speed and blade stability. The blade deploys and retracts linearly from the front of the handle, fully automatic in both directions within a split second. Microtech defined the OTF category, setting the standard with the HALO in 1995 and the iconic Ultratech in 1999. Since then, the lineup has expanded to include models like Dirac, Dirac Delta, Exocet, Combat Troodon, and Scarab II — all benchmarks for EDC users and professionals alike. The latest Ultratech generations feature revolutionary ZBT (Zero Blade Play Tolerance) technology, which eliminates blade play post-lockup, along with an enlarged actuator and service-friendly architecture allowing fine-tuning without compromising reliability. Combat Troodon Gen III also introduces a dual-fuel drivetrain and re-engineered actuator pocket to reduce friction and flush out debris — resulting in smooth operation even in dusty environments. Many OTFs also utilize a “resting” spring design, where the spring is relaxed in both open and closed positions, extending the mechanism's service life. The result? An automatic tool with tight tolerances, fast action, and outstanding repeatability — built for users who depend on OTFs every single day.
