About Zero Tolerance
Zero Tolerance has been producing premium hard-use folding and fixed-blade knives in Tualatin, Oregon since 2006, applying aerospace-grade materials and precision manufacturing to tools designed for military, law enforcement, and serious knife users who accept no compromises.
Heritage & History
Zero Tolerance was launched in 2006 as a premium hard-use sub-brand within KAI USA, the American manufacturing arm of the Japanese parent company that also produces Kershaw knives. The brand was built from the ground up around a specific customer profile: military personnel, law enforcement officers, and knife enthusiasts who needed production knives performing at near-custom levels. Zero Tolerance's founding premise was that no compromise would be made in materials or construction to hit a price point.
That uncompromising approach shaped every early design decision — premium steels like S30V and later CPM 20CV and S35VN became standard, titanium frame locks replaced steel liners, and manufacturing tolerances were held tighter than most production knife companies considered economical. The brand quickly built a devoted following among the tactical and collector knife communities, with limited production runs routinely selling out and commanding premiums on the secondary market.
Made in Tualatin, Oregon
Zero Tolerance knives are manufactured at the KAI USA facility in Tualatin, Oregon, where the company's full production infrastructure — CNC machining, heat treating, hand finishing, and quality inspection — operates under one roof. The Tualatin plant produces both the Kershaw and Zero Tolerance lines, with ZT products receiving the premium steel specifications and tighter tolerance requirements that define the brand.
The Oregon facility's investment in precision CNC equipment allows Zero Tolerance to machine titanium handles, carbon fiber overlays, and premium steel blades to the tolerances that produce the smooth, rattle-free action ZT owners expect. Handle-to-blade fit and pivot smoothness are evaluated by hand before any knife leaves the factory, a quality control step that distinguishes the brand from production knife manufacturers relying entirely on automated inspection. The combination of American manufacturing infrastructure and no-compromise specifications is the core of what Zero Tolerance offers.
