This Zero Tolerance sprint run gives the 0055 a BlackWash™ blade and deep bronze anodized titanium handles.

The 0055BRZ is a darker take on the 0055, which was based on the exciting Airborne folder by Gus T. Cecchini of GTC Knives. Like the original, the 0055BRZ offers dramatic aerodynamic lines on both the blade and handle and ZT’s meticulous precision build. The dynamic blade is CPM 20CV stainless steel, a formula that provides enhanced toughness and resistance to edge chipping with no loss of wear resistance and a sharp, long-lasting edge.

The handles are 3D-machined titanium with a titanium frame lock and hardened steel lockbar insert, then anodized in a unique deep bronze. The custom backspacer is anodized aluminum in matte black, and the rest of the hardware is also subtle black.

The 0055BRZ features Gus' SLT hidden flipper tab. While the knife is closed, the flipper is concealed. When you’re ready to open it, pull back on the SLT. A spring flips the tab up into position. Then just pull back on the tab and the 0055BRZ opens just like any other ZT. The hidden SLT ensures there’s no flipper tab poking up along the spine or beneath the handle to interrupt the sleek lines of the 0055BRZ. The 0055BRZ’s blade glides out of the handle on ZT’s KVT ball-bearing system, ready for use. The action is similar to a two-stage rifle trigger and is completely addictive. To complete this exemplary knife, ZT added a left/right reversible bent titanium clip.
