Zero Tolerance

Zero Tolerance – Zero Tolerance for anything but the best.

The tough, solid knives from Zero Tolerance are designed for professional use. These are highly reliable products that are meticulously crafted down to the smallest detail. For years, professional military personnel, police forces, firefighters, as well as members of rescue and emergency teams have relied on the high standards set by Zero Tolerance.

The knives from Zero Tolerance are designed by Strider Knives in collaboration with designers such as Ken Onion, Rick Hinderer, Todd Rexford, and Dimitry Sinkevich, and are completely manufactured in America. The designs of Zero Tolerance are unique and very elegant, making them popular collector's items worldwide. Particularly popular and well-known are the models 0550 and 0560, which were created in collaboration with Rick Hinderer.

When it comes to the production of ZT knives, only the highest quality materials are used, which is why they are said to have the stability of a tank. Take, for example, the American super steel S35VN, which is often used by Zero Tolerance as blade steel. It is a stainless steel yet incredibly hard, high-quality powder steel with excellent microstructural stability, grindability, and toughness, making it a top-of-the-line steel.

Zero Tolerance is a brand of Kai USA Ltd. The brand Zero Tolerance (ZT) first appeared 2006 when they saw a demand in the American market for a Made-in-USA line of knives that would meet the needs of military and law enforcement professionals, as well as other first responders such as firefighters and medical emergency personnel.

The first products of Zero Tolerance were primarily combat knives. But since then, the line has expanded to include a variety of general and high-quality knives. From larger and heavier outdoor knives to slimmer and lighter everyday carry knives (EDC knives) crafted to the high-performance standards of Zero Tolerance, ZT delivers top quality to an increasing number of knife owners worldwide.

Zero Tolerance knives are made from high-quality materials such as S30V, S35VN, or 20CV blade steel, and G10, titanium, and carbon fiber handle scales.
