ZT - Zero Tolerance
Zero Tolerance for anything less than the best
We will continue to build the kind of premium-quality, professional knives that our customers can depend on every single day.
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, such as the military, law enforcement, and other first responders, such as firefighters and emergency medical personnel.
