Ultratech Gen IV – The Next Evolution in OTF Innovation

The Ultratech Gen IV continues Microtech’s legacy as the benchmark for out-the-front automatic knives, now refined with updates based on user feedback. Unlike previous generations, Gen IV does away with the Zero Blade Play (ZBP) system, simplifying the build while focusing on smoother, more reliable mechanics. The result is the same iconic Ultratech feel—just sharper and more confident.

This double-edge version features a 3.5″ Bohler M390MK stainless dagger blade with a stonewash finish, paired with a bold red anodized aluminum handle. Fully automatic deployment and retraction are controlled by the thumb slide, while a glass breaker and pocket clip make it a practical everyday companion.

Note from Lone Star Knife & Supply

The Ultratech has always been the standard for OTFs, and the Gen IV keeps that reputation alive. This red handle version pops in the pocket while still offering the same dependable action and Microtech quality you expect.
