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.

  1. Zero Tolerance - Sinkevich Folder Titanium - ZT0450 - knife

    The original Zero Tolerance 0454 was an award-winning collaboration between ZT and custom knife designer Dmitry Sinkevich. But it was also a very Limited Edition knife.

    So ZT is doing something about that with the new 0450. While based on the original’s streamlined form and high-performance function, this new and more compact version will be much more readily available. With its 3.25-inch blade and lightweight-yet-stronger-than-steel titanium handles, the 0450 has a sleek and sophisticated look that, we think, makes it a perfect EDC.

    ZT built it with an S35VN stainless blade that sharpens to a razor edge, holds it well, and can be resharpened easily. The knife opens smoothly and easily with the KVT ball-bearing opening system and built-in flipper. A titanium frame lock with hardened steel lockbar insert ensures solid lock up. Polished pivot hardware just adds to the 0450's refined good looks.

  5. Zero Tolerance - R.J. Martin Folder Titanium - ZT0609 - knife

    The new Zero Tolerance 0609 is a smaller, even more carry-ready version of the original Factory Custom 0606CF from ZT, RJ Martin, and Matt Martin. Like the original, it offers a clean, streamlined look yet also has highly detailed handle machining that adds both grip and visual impact. For even more visual “wow,” the 3D-machined handle is built of light-yet-strong titanium that ZT has anodized in an attractive bronze.

    The 3.4-inch blade is CPM 20CV, which provides enhanced toughness and resistance to edge chipping. It also delivers superior hardness, corrosion resistance, and excellent edge retention. The drop-point blade has a two-tone finish: machined satin on the grinds with a stonewashed finish on the flats. The new 0609 opens manually with ZT’s KVT ball-bearing opening system and the handy flipper so it’s always ready when you want it.

    Last—but certainly not least—you’ll notice the oversized See-Through Pivot (STP). Designed by RJ Martin, this unique, pivot is hollow in the center, letting you “see through” it. The See-Through Pivot adds another intriguing touch to this already-attractive knife.

  11. 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.
