ZT has given the original 0450 a makeover and has resulted in the beautifully darker version 0450CF. This knife consists of a S35VN blade great for its exceptional wear resistance and edge retention as well as a carbon fiber front and black DLC coated titanium back handle. To enhance the look of the 0450CF ZT added two emerald green back spacers that standout amongst the all black blade and handle. 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.
