Understanding the Zero Tolerance 0556 Automatic Knife

The Zero Tolerance 0556 series delivers a refined side-opening automatic experience, blending premium CPM-MagnaCut steel with a sophisticated titanium and carbon fiber handle. This series is designed for users who want a slim, high-performance everyday carry tool that prioritizes precision and slicing efficiency.

What kind of steel does the ZT 0556 use?
The Zero Tolerance 0556 series is equipped with CPM-MagnaCut steel, a high-performance material known for its excellent balance of edge retention, toughness, and corrosion resistance. You can learn more about the properties of this specific alloy in our guide to what is MagnaCut steel.
Is the 0556 series designed for heavy duty use?
The 0556 is better suited for gentlemanly EDC and general cutting tasks rather than hard-use or aggressive tactical roles. Its thin, slicy blade with a high flat grind is optimized for precision work, making it an ideal choice for a pocket knife used in daily office or suburban environments.
How does the pocket clip attach to the handle?
The deep carry clip on the 0556 series is mounted internally, which prevents screws from snagging on your pocket and allows the knife to sit extremely low for discreet carry. Additionally, the clip is reversible to support both left and right-handed users.
What is the blade profile on this automatic knife?
The 0556 features a 3.35 inch drop point blade with a hint of curvature along the spine, giving it a profile that nearly resembles a straight clip point. For more information on how this geometry performs compared to other styles, visit our blade shapes guide.
What materials are used for the handle construction?
Every variant in the 0556 series features a titanium handle with textured carbon fiber inlays. This combination provides a lightweight yet durable frame with a premium feel and added grip, while a broad, textured button ensures reliable deployment of the automatic action.
