The original Zero Tolerance 0454 was an award-winning collaboration between ZT and custom knife designer Dmitry Sinkevich. But it was also a very Limited Edition knife.To make this amazing knife more readily available, ZT has created a new version based on the original's streamlined form and high-performance function. The 0452CF is the same size as the original 0454, but with a carbon fiber front scale and S35VN dual-finished blade. S35VN sharpens to a razor edge, holds it, and can be resharpened easily. The 0452CF opens as smooth as butter with the KVT ball-bearing opening system and built-in flipper. A titanium frame lock with hardened steel lockbar insert ensures solid lock upAs a final touch of class, the 0452CF features handsome 5-spoke pivot hardware. From office to outdoors, the 0452CF is ready to go wherever you're ready to take it. FeaturesKVT ball-bearing systemEasy to resharpen
