The Microtech Ultratech Gen III ZBP 1121-11 is a premium out-the-front (OTF) automatic knife engineered for precision, durability, and elite everyday carry performance. Built with Microtech’s latest Gen III platform, this model delivers enhanced reliability, smoother action, and improved internal tolerances.

The 3.5-inch blade is crafted from high-performance Bohler M390 steel, offering exceptional edge retention, corrosion resistance, and long-lasting sharpness. Finished in a rugged stonewash, the blade provides excellent wear resistance while helping conceal scratches from regular use. The partially serrated edge increases cutting versatility, making it ideal for rope, webbing, and tougher materials.

Equipped with Microtech’s advanced dual-action OTF mechanism, the Ultratech ensures fast, smooth, and consistent blade deployment and retraction. The integrated ZBP (Zero Blade Play) system enhances lockup stability, minimizing blade movement and providing a more solid, confidence-inspiring feel during use.
