Since 2006, Zero Tolerance Knives - or ZT Knives, as their dedicated fans sometimes say - has been producing knives for people who have no margin for error. Their merger of function and performance, along with prices lower than most high-end knives, has made Zero Tolerance a favorite among first responders and knife fanatics alike. Owned by Kai USA Ltd. along with Kershaw, Zero Tolerance knives are produced using extremely high manufacturing tolerances and top-shelf materials.
