Ultratech Gen III ZBP – Precision At Your Fingertips

The Microtech Ultratech Gen III ZBP (Zero Blade Play) is a standout in automatic knife engineering. Featuring a 3.50″ double-edge Bohler M390MK dagger blade, stowed behind a zero-blade-play chassis, and activated with a clean, precise double-action thumb slide, this knife represents the pinnacle of Microtech’s OTF perfection. 

Note from Lone Star Knife & Supply

This is the OTF I reach for in every auto-friendly scenario. The action is crisp, the deployment and retraction are reliably smooth, and that Zero Blade Play makes every flick feel locked in. At just ~3.8 oz, it carries clean yet performs like a heavyweight. This Gen III upgrades a proven platform with modern handling and feature set.
