Zero Tolerance knife: for professional use

Zero Tolerance: heavy-duty and American

Zero Tolerance knives are designed by Ken Onion, among others, in collaboration with Strider Knives. They are manufactured entirely in the United States. Some of Zero Tolerance's most popular knives are the 0550 and 0560 knife, developed with Rick Hinderer. The materials that are used are very robust and the blades are 'built like a tank'. A number of knives, including the 0350, feature the SpeedSafe® assisted opening system. This opening system ensures that the knives are very easy to open with one hand.

Zero Tolerance series

Zero Tolerance 0006

The 0006 is a large, robust survival knife inspired by the ZT-9 bayonet, originally a Mick Strider design. The name of the 0006 is inspired by the 6-inch blade of this ZT-9. Built for outdoor use, this knife will never let you down.

Zero Tolerance product types

The Zero Tolerance pocket knives are unique and very collectible. They're made of premium materials such as CPM steel, titanium and carbon fibre. Among the pocket knives, you will see that knives with a low serial number are a lot more massive than later series. There's something for everyone.

Zero Tolerance offers a range of both pocket knives and fixed blades. The brand's large robust survival knives are particularly sought after.

About Zero Tolerance

Zero Tolerance is a brand founded in 2006 that manufactures premium utility knives for heavy duty work. The brand started with big robust knives for military, police and other professionals. Combat knives in particular were manufactured in the beginning. The knives also caught on with normal citizens and, since 2009, Zero Tolerance has been making more compact pocket knives that can also easily fit in your pocket.
