We are proud to introduce Zero Tolerance knives. Zero Tolerance Knives are manufactured of premium materials such as S30V, S35VN, or CTS-204P blade steel and G-10, titanium, and carbon-fiber handle scales. Operation is conspicuously smooth and ZT fit and finish is second to none. Collectors have described ZTs as a “real beast”. All ZTs are proudly "Overbuilt" in Tualatin, Oregon.
