The Microtech Ultratech Gen III ZBP 1121-1BL delivers a clean, tactical look with its blue anodized aluminum handle paired with a stealthy black-finished blade. Built on the advanced Gen III Ultratech platform, this model enhances Microtech’s flagship OTF design with tighter tolerances, improved internals, and superior lock-up performance.
At the heart of the knife is a 3.5-inch double-edge dagger blade crafted from premium Böhler M390 steel, known for its outstanding edge retention, corrosion resistance, and durability. The black blade finish reduces glare and adds a rugged, low-profile aesthetic, while the dagger profile offers excellent piercing capability and balanced dual-edge performance.
This Gen III version incorporates Microtech’s ZBP (Zero Blade Play) system, a major innovation that minimizes blade movement when deployed, resulting in a more solid and confidence-inspiring feel—closer to a fixed blade compared to traditional OTF knives.
