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.

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.
