Zero Tolerance Knives

Zero Tolerance, a division of Kai USA Ltd., introduced itself to the market in 2006 with a commitment to crafting hard-use knives tailored for professionals. Initially focusing on combat knives, the line swiftly expanded to encompass a range of premium knives suitable for various applications. From robust outdoor knives to sleek everyday carry options, all ZT knives embody top-tier quality.

Constructed from premium materials such as S30V, S35VN, or CTS-204P blade steel paired with G-10, titanium, or carbon-fiber handles, these knives offer exceptional durability. Operating smoothly and displaying impeccable fit and finish, ZT knives are revered for being impressively sturdy—often described as “overbuilt” and robust. Crafted by skilled artisans at the Tualatin, Oregon USA manufacturing facility, Zero Tolerance knives uphold high-performance standards.

As a brand under Kai USA Ltd., a significant manufacturer and distributor in Japan renowned for disposable razors, surgical tools, personal care items, and housewares, Zero Tolerance continues to represent excellence in the knife industry.
