The Microtech Ultratech GEN III ZBP OTF Auto S/E Black Part Serrate Tactical represents the next evolution of one of the most iconic out-the-front automatic knives ever built. Since its introduction in 1999, the Ultratech has earned a reputation for uncompromising quality, precision engineering, and dependable performance. The Gen III platform raises the bar even higher, combining proven design with groundbreaking innovations that make this knife smoother, stronger, and more refined than ever before. Built for professionals, enthusiasts, and anyone who demands excellence from their everyday carry, this Ultratech is engineered to perform when it matters most.
At the center of the knife is a 3.55" single-edge blade crafted from premium Böhler M390MK steel. Renowned for exceptional edge retention, corrosion resistance, and toughness, M390MK provides the durability needed for hard use while maintaining a razor-sharp edge. The tactical black finish minimizes glare and gives the knife a purpose-built appearance, while the partially serrated edge adds versatility for slicing through rope, webbing, and other tough materials without sacrificing the precision of a plain cutting edge.
The lightweight yet rugged 6061-T6 aluminum handle offers outstanding strength without unnecessary bulk. Measuring 8.54" overall and weighing just 3.61 ounces, the Ultratech carries comfortably while providing a secure, confident grip. Precision-machined and secured with Torx hardware, every component reflects Microtech's commitment to premium craftsmanship. An upgraded glass breaker completes the design, adding valuable emergency capability without compromising the knife's streamlined profile.
The Gen III Ultratech introduces several of Microtech's most significant mechanical advancements. Its innovative Dual-Fuel Drive Train™ delivers exceptionally smooth and consistent deployment and retraction, while Crud Kutter™ technology helps clear debris from the internal mechanism to keep the action running reliably in demanding conditions. The standout feature is Zero Blade Play (ZBP), an advanced engineering achievement that dramatically reduces blade movement when deployed, providing a remarkably solid feel that sets a new standard for out-the-front automatic knives.
Every push of the thumb slide delivers fast, authoritative deployment backed by Microtech's legendary precision. Whether you're carrying it for work, emergency preparedness, or simply appreciating one of the finest automatic knives available, the Ultratech GEN III ZBP offers the confidence that comes from decades of continuous refinement. It's a premium OTF that blends cutting-edge technology, exceptional materials, and tactical styling into a package that's built to exceed expectations every time it's called into action.
