Years of production

[L2bravo]

I'm fairly new to ZT knives. However, I am finding myself liking them more than my Spydercos, and BM's. I really like the fact that they use good materials, have a great warranty, and are built like hell. Which made me start wondering, "how long have these been in production"?

Models like the 30X, 350, 200, 550, 561? I'd love to know more. Please share if you know.

The first ZTs came out in early 2006 with the 0200, 0100, 0300 and 0400.

ZERO TOLERANCE KNIVES

Zero Tolerance builds the kind of premium-quality, professional knives that you can depend on every single day.

The brand made its first appearance in 2006 when Kai USA, the makers of Zero Tolerance, saw a place in the market for a made-in-the-USA line of hard-use knives that would meet the needs of professionals, such as the military, law enforcement, as well as other first responders, including fire fighters 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. Although Zero Tolerance knives are larger, heavier knives, many customers won’t have anything else as an everyday carrying knife.

Zero Tolerance incorporates the most advanced materials and technologies in a tool that has been with us from the beginning. And they’re still evolving…
