"Zero Tolerance for anything but the best." Also known as "ZT", Zero Tolerance produces some of the finest production knives that money can buy. ZT is the beefy big brother of pocket knife favorite Kershaw. With the use of top quality blade materials and compounding techniques, these completely American made knives are among the best production knives in the world.
Zero Tolerance Knives are manufactured of premium materials and the operation is conspicuously smooth. The ZT fit and finish is excellent. ZT customers have described ZTs as a "real beast" and—proudly—"overbuilt."
Zero Tolerance is a brand of Kai USA Ltd. The ZT brand first made its appearance in 2006 to address the need 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 their Tualatin, Oregon USA manufacturing facility by their most skilled workers.
