Zero Tolerance Knives

Hard-Use Premium and Professional Knives

Designed and manufactured to stand up to heavy-duty use, Zero Tolerance Knives are built of premium materials. The knives have earned a reputation among their devoted fans as being “built like a tank” or a “real beast” or even being—proudly—”overbuilt”.

Zero Tolerance is a brand of Kai USA Ltd. The ZT brand first made its appearance in 2006 when they 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.

The initial products were combat knives, but since that time, the line has expanded to include a variety of general-use and premium knives. From larger and heavier outdoor knives to slimmer and lighter every day carrying knives that are still “built like a tank,” ZT knives always provide knife owners with top-of-the-line quality.

Zero tolerance produces some of the very best tactical knives out there. With the help of collaborators like Ken Onion and Tim Galyean and with blades like Böhler N690, CPM-S30V, and ELMAX stainless, Zero Tolerance have steady climbed the ladder of success not only in producing higher quality folding knives but innovating them. The fact that all of their knives are made in the good ‘ol United States is just icing on the cake.
