The Microtech Ultratech ZBP OTF Automatic Knife in Dark Burnt Bronze brings together proven performance, precision engineering, and rugged styling in one of the most recognizable platforms in automatic cutlery. As Microtech's flagship out-the-front knife, the Ultratech has set a high standard since its introduction in 1999. This updated Gen III model builds on that legacy with advanced internal components, refined construction, and the innovative Zero Blade Play system. Finished in a striking dark burnt bronze across both the blade and handle, this Ultratech delivers a cohesive, tactical appearance that stands out in any collection.
At the heart of this knife is a 3.55-inch tanto blade crafted from premium M390MK stainless steel. Known for its excellent edge retention, wear resistance, and corrosion resistance, M390MK is built to handle demanding cutting tasks while maintaining a dependable edge. The tanto profile features a reinforced point and angular geometry, giving the blade a distinctive appearance and making it well suited for utility cutting. Its dark burnt bronze finish adds a rugged look that complements the matching handle while providing a cohesive finish throughout the knife's design.
The Ultratech's double-action out-the-front mechanism allows the blade to deploy and retract with a simple movement of the thumb slide. Microtech's updated Zero Blade Play internals are engineered to minimize blade movement when deployed, supporting a solid, precise feel during use. The Gen III design also incorporates the Crud Kutter system and Dual-Fuel Drive Train, reflecting Microtech's continued focus on improving the operation and reliability of its automatic platforms. These refinements build on the Ultratech's established design while bringing updated engineering to a proven favorite.
The handle is constructed from durable 6061-T6 aluminum, offering a strong, lightweight foundation for everyday carry. Torx screw construction provides a clean, precision-built appearance, while the integrated glass breaker adds a practical emergency feature. With an overall length of 8.54 inches, the Ultratech offers a substantial grip and full-size profile without losing the streamlined character that has made this platform so popular among automatic knife enthusiasts.
Combining premium M390MK steel, a refined double-action OTF mechanism, and a matching dark burnt bronze finish, the Microtech Ultratech ZBP delivers modern performance backed by decades of design evolution. It's an excellent choice for collectors and experienced knife enthusiasts who appreciate advanced engineering, distinctive styling, and the enduring legacy of Microtech's flagship automatic knife.
