Zero Tolerance 0556BLK Overview
The Zero Tolerance 0556BLK is explicitly engineered as an all-business, all-black automatic folder that combines refined power with a bold monochromatic look. Consequently, it utilizes high-performance CPM MagnaCut steel to deliver an exceptional balance of superior edge retention, extreme toughness, and impressive corrosion resistance. Furthermore, this precise drop point blade features a slicey flat grind and a precise heat treatment reaching 62-64 HRC for lasting durability during professional tasks. Ultimately, this exceptional metallurgical setup, finished with a jet-black PVD coating and a fine ceramic bead blast, makes it a flawless companion for any stealthy tactical or duty occasion.
Reliable Construction
Deployment is incredibly fast and authoritative with a simple push of the stylish, trapezoid-shaped button. Moreover, the blade is securely held open by a rugged push-button lock, ensuring maximum safety and absolute reliability during intense use. Additionally, the combination of a black PVD-coated titanium handle and elegant carbon fiber inserts provides incredible structural integrity while maintaining a remarkably light weight of 2.4 oz.

Ergonomic Control
User comfort is a primary focus of this slim and sophisticated design. Therefore, the titanium handle with carbon fiber inlays on both sides provides an incredibly secure and hand-filling grip without adding unnecessary bulk to your tactical kit. Furthermore, it includes a versatile, reversible extra-deep-carry pocketclip for discreet, low-profile carry on either side, tip-up. As a final unified touch, the 0556BLK features black-oxide hardware and a black Cerakote pocketclip for a complete blackout aesthetic.
