Zero Tolerance

Zero Tolerance Knives have been described by customers as real beasts and proudly overbuilt. These knives represent the tactical line of Kai USA Ltd, which was established in 1996. The history of these blades stretches back even further. The Japanese company Kai Group opened in 1908 in Seki, a city where phenomenal blades have been crafted for 800 years. Kai produces blades for everything from grooming, cooking, beauty care and the medical field. With Zero Tolerance, the company started making combat knives, then expanded to include heavy-duty outdoor blades and every day carry folding knives. Zero Tolerance knives utilize the finest materials and craftsmanship. EMTs, law enforcement officers, military personnel, firefighters and more can depend on these tactical blades.
