Microtech Signature Series Ultratech EX-ZBP Gen III Stonewash Hellhound S/E Black AUMT1119EX10S

The Microtech Ultratech Gen III OTF Automatic Knife represents the benchmark for out-the-front performance, refining the platform that helped define modern automatic knives. Known for its reliability, speed, and precision engineering, the Ultratech continues to lead the category with meaningful upgrades and proven durability in a sleek, carry-friendly design.

The 3.35" drop point blade is crafted from Microtech’s proprietary Böhler M390MK stainless steel, an exclusive alloy developed in collaboration with Böhler engineers. This upgraded steel builds on the strengths of M390 with improved edge retention and corrosion resistance while maintaining excellent toughness for demanding use. The blade features a rugged stonewash finish that reduces glare and helps conceal wear from everyday carry.

Deployment is handled by a dual-action out-the-front automatic mechanism powered by Microtech’s Dual Fuel Drive system, delivering fast, consistent blade action. The Gen III Ultratech also introduces the advanced Zero Blade Play (ZBP) system, which significantly reduces blade movement when deployed, setting a new standard for lockup stability in OTF designs.

The handle is constructed from black aircraft-grade aluminum, offering a lightweight yet highly durable frame built for long-term use. A stainless steel ambidextrous pocket clip provides secure carry, while an integrated glass breaker and lanyard hole add practical utility for emergency situations.

This updated Gen III model includes Krud Kutter grooves on the thumb slide to help reduce pocket debris interference, a ceramic thumb ball on the clip to minimize wear, and upgraded Torx hardware for improved durability across the entire platform.

Measuring 5.01" closed and weighing 3.5 ounces, the Ultratech remains compact enough for everyday carry while delivering serious cutting capability. Every knife is proudly made in the USA with the precision and quality that define Microtech.
