Zero Tolerance Knives

Zero Tolerance is a brand of Kai USA Ltd. Kai is a major manufacturer and distributor of disposable razors, surgical tools, personal care products, and housewares in Japan. 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. All ZTs are built in our Tualatin, Oregon USA manufacturing facility by our most skilled workers.
