Be sure to sign up for email/text notifications on this listing to be the first to know when we will be dropping the next batch of Ultratech ZBT OTFs. The Microtech Ultratech ZBT (Zero Blade Tolerance) embodies all of Microtech's recent achievements. And like the densely packed gunpowder in a bullet casing fires a round thousands of feet, the densely packed features in this knife propel the OTF world into the future. Let's get right to the star of the show: the Ultratech ZBT has zero blade play. Those familiar with OTFs know how rare that is on double-action models; it's rare because it's so difficult to implement. But Microtech has done a fantastic job with their Zero Stop mechanism, which is user-serviceable, not bulky, and reliable. It functions by wedging the blade against the chassis via a cone-like component that has been precision-tuned to the exact right position. Microtech has been making many upgrades to its OTFs in recent months, and all of those upgrades made it into the Gen 3 Ultratech: The new Ultratech further distinguishes itself from its predecessor with improved gimping, a slightly wider handle, a slightly longer and wider blade, a lower-profile glass breaker that's integrated into the handle, a wider thumb slide, a titanium pocket clip with a silica carbide ball, and Torx hardware. As with Microtech's other Gen III OTFs, a lanyard hole runs through the large base screw that secures the pocket clip, and the pocket clip is reversible for left-handed users. The knife's blade and handle thickness match that of the former iteration. The cherry on top of this out-the-front sundae is that the Ultratech ZBT is accessibly priced, ensuring everyone who wants the best of the best can get it. The future of OTF knives is here; get your Ultratech ZBT today and be a part of it.
