Collection: Zero Tolerance

Zero Tolerance Knives (ZT), a premium brand under Kai USA Ltd., was established in 2006 to cater to professionals in military, law enforcement, and emergency services. Based in Tualatin, Oregon, ZT quickly gained recognition for its "proudly overbuilt" knives, designed to withstand rigorous use. Early collaborations with renowned custom knifemakers like Ken Onion and Strider Knives led to robust models such as the ZT 0200 and the 0500 M.U.D.D., setting a high standard for durability and performance .

As the brand evolved, ZT expanded its offerings beyond tactical applications to include everyday carry (EDC) knives, without compromising on quality. The introduction of the ZT 0350 in 2009 exemplified this shift, combining a more compact design with premium materials, appealing to a broader audience . ZT's commitment to excellence is evident in its collaborations with designers like Rick Hinderer, Dmitry Sinkevich, and R.J. Martin, resulting in award-winning models such as the ZT 0777 and ZT 0454, which have been recognized at the Blade Show for their innovation and craftsmanship .

The Zero Tolerance logo, featuring a bold "ZT" within an oval, symbolizes the brand's dedication to strength and precision. This emblem is prominently displayed on their knives, reflecting the company's identity and commitment to quality.
