The Zero Tolerance brand first made its appearance in 2006 when we saw a place in the market for a Made-in-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 20CV, S30V, or S35VN blade steel and G10, titanium, and carbon-fibre handle scales. We pay attention to the details, ensuring each part of your ZT is built with care and precision. Operation is conspicuously smooth and ZT fit and finish is second to none. All ZTs are proudly built in our Tualatin, Oregon USA manufacturing facility by our most skilled workers.
