The Zero Tolerance 0055 is unlike anything you've ever seen--unless you've seen the exciting Airborne folder by Gus T. Cecchini of GTC Knives. And while the Airborne was where we started, the ZT-GTC collaboration took off from there. The result is the new 0055, which offers dramatic aerodynamic lines on both blade and handle and ZT's meticulous precision build. The dynamic blade is S35VN stainless steel, a formula that provides enhanced toughness and resistance to edge chipping with no loss of wear resistance. It is rich in niobium, vanadium, and chromium carbides and ensures the 0055 has a sharp, long-lasting edge.
