Zero Tolerance Knives
18600 SW Teton Ave.
Zero Tolerance is a brand of Kai USA Ltd. The ZT brand first made its appearance in 2006 when we saw a place in the market for a Made-in-the-USA line of hard-use knives that would meet the needs of professionals in the military and law enforcement, as well as other first responders, such as firefighters and emergency medical personnel.
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. Our customers have described ZTs as a “real beast” and—proudly—"overbuilt." All ZTs are built in our Tualatin, Oregon USA manufacturing facility by our most skilled workers.
