The 0450 is a more compact version of Dmitry Sinkevich and Zero Tolerance?s design of the limited edition and award winning 0454. The S35VN steel blade comes in a stonewash and satin finish while the handle comes in a stonewashed titanium finish. The KVT ball-bearing system make the 0450 easy to open and with the frame lock and hardened steel lockbar insert it stays open. Zero Tolerance had only a few things in mind when creating and designing their knives. They wanted to make them with top of the line materials as well as being able to stand up to heavy-duty use. A lot of their knives are in collaboration with top knife makers such as Rick Hinderer, Todd Rexford, Jens Anso and Dmitry Sinkevich. Zero Tolerance initially only produced combat knives but have since added a variety of everyday carrying and premium knives, built with the same ?OVERBUILT? designs as their knives that are tailored towards military and law enforcement.
