Overview

The Microtech Ultratech EX-ZBP Bayonet Signature Series represents the apex of OTF automatic knife engineering. This Signature Series model combines the revolutionary Zero Blade Play (ZBP) technology with a distinctive stonewash-finish fully serrated bayonet blade in Bohler M390MK steel. The ZBP system virtually eliminates all blade movement when deployed, delivering a locked-open feel that rivals a fixed blade.
