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. So ZT is doing something about that with the new 0450. While based on the original’s streamlined form and high-performance function, this new and more compact version will be much more readily available. With its 3.25-inch blade and lightweight-yet-stronger-than-steel titanium handles, the 0450 has a sleek and sophisticated look that, we think, makes it a perfect EDC. ZT built it with an S35VN stainless blade that sharpens to a razor edge, holds it well, and can be resharpened easily. The knife opens smoothly and easily with the KVT ball-bearing opening system and built-in flipper. A titanium frame lock with hardened steel lockbar insert ensures solid lock up. Polished pivot hardware just adds to the 0450's refined good looks.
