Zero Tolerance

The Zero Tolerance brand first made its appearance in 2006 when we saw a place in the market for a Made-in-USA line of hard-use knives that would meet the needs of professionals in the military and law enforcement, as well as other first responders, such as firefighters and emergency medical personnel.

The initial products were combat knives, but since that time, the line has expanded to include a variety of general use and premium knives. From larger and heavier outdoor knives to slimmer and lighter everyday carrying knives that are built to ZT's high-performance standards, ZT knives always provide knife owners with top-of-the-line quality.

  2. Zero Tolerance - Strider Onion - Tigerstripe Black G10 - ZT0303 - PRIVATE COLLECTION - knife

    Knife from a private collection - Iconic and sought after model designed by Ken Onion and Mick Strider - Out of production and no longer available - Perfect in all, like new, serial 1544, does not have any kind of sign or defect - The knife shows an uncertainty at the tip, on the sharpening, which is slightly different; presumably already produced in this way by ZT - The sharpening is good and shows no signs of wear, presumably the sharpening is the original factory - Accompanied by original Zero Tolerance box, but referred to the model 0301 with green G10 handle - Checked and certified by our internal laboratory

  21. Zero Tolerance - Rexford Folder Titanium Blu-ray Sprint Run - ZT0808BLU - Knife

    The Zero Tolerance 0808BLU, with blue-anodized handle, is a sprint run built in a limited quantity.

    The 0808 is a collaboration between ZT and custom knifemaker Todd Rexford and is based on his Cesium model. It features advanced-formula stainless steel and ZT’s smooth-as-silk KVT opening system. The 0808’s blade is built of Crucible S35VN stainless steel. This powdered metallurgy steel is extremely fine-grained so it can be sharpened to a razor edge. Added niobium and nitrogen enhance toughness to resist chipping and provide excellent edge retention. Yet it’s also easy to re-sharpen.

    Opening is fast and simple with KVT. Caged ball bearings surround the pivot to make the blade quick and easy to open using the built-in flipper. With KVT, the 0808 is as easy to open as any assisted knife, but without the need for a spring.

    The 0808GLD’s blade is paired with chamfered titanium handles that provide a solid, comfortable grip. The sturdy frame lock has a hardened steel lockbar insert to offer extra-secure, extra-solid blade lock up. The reversible pocketclip enables you to carry comfortably left- or right-handed.

    This blue-anodized edition of the 0808, the 0808BLU, is a sprint run. Quantities are limited. Check with your local ZT dealer for availability.

  25. Zero Tolerance - Rexford Folder Titanium - ZT0808 - knife

    The Zero Tolerance 0808 is our latest piece of pocket technology. It's a collaboration between ZT and custom knifemaker Todd Rexford and is based on his Cesium model. But the technology here isn’t circuits and wires. Instead, it’s advanced-formula stainless steel and ZT’s smooth-as-silk KVT opening system.

    The 0808’s blade is built of Crucible S35VN stainless steel. This powdered metallurgy steel is extremely fine-grained so it can be sharpened to a razor edge. Added niobium and nitrogen enhance toughness to resist chipping and provide excellent edge retention. Yet it’s also easy to re-sharpen.

    Opening is fast and simple with KVT. Caged ball bearings surround the pivot to make the blade quick and easy to open using the built-in flipper. With KVT, the 0808 is as easy to open as any assisted knife, but without the need for a spring.

    The 0808’s blade is paired with chamfered titanium handles that provide a solid, and very durable, grip. The sturdy frame lock has a hardened steel lockbar insert to offer extra-secure, extra-solid blade lock up. The reversible pocketclip enables you to carry comfortably left- or right-handed. Move over, iPhone. The 0808 deserves pocket space.
