Zero Tolerance is a series of knives from KAI that focused on building professional-grade combat knives designed to survive harsh conditions. These are tough, high quality knives with high end steel, overbuilt locks, assisted openings and all sorts of other cool goodies that tactical knife enthusiasts enjoy.
I recommend buying Zero Tolerance knives at Amazon.

Zero Tolerance Knife Reviews:
I have had the pleasure and fortune to review a number of ZT knives. What follows is all of my Zero Tolerance reviews:
- Zero Tolerance ZT 0450 Review
Despite positioning itself as a maker of hard use tools for hardcore individuals, Zero Tolerance has always had more universal appeal than its marketing would suggest – and I don’t think the company’s appeal has ... continue reading
- Zero Tolerance 0900 Review
Alright, peer pressure, you win. You finally got to me. After holding out for god knows how long, I finally jumped on the titanium-flipper-framelock (henceforth TFF) bandwagon. Not just any TFF, mind: if I’m challen ... continue reading
- Zero Tolerance 0888MAX
First of all, this is not really a review. The 0888MAX is a pure collectible for me. A collectible I was able to acquire through a trade with my good friend Andrew of the Edge Observer. The knife has been admired and ... continue reading
- Zero Tolerance 0452CF Review
When it comes to folding knives, I am extremely selective in what I choose to carry, especially if it is a blade that I am going to carry for self-protection. It has to be light, reliable, sharp, and geometrically ef ... continue reading
- Zero Tolerance 0808 Review
Zero Tolerance has had some interesting releases in 2015. What especially intrigued me was their addition of a few smaller folders to the line up. The 0450, 0900 and
- Zero Tolerance 0620CF Review
I have given Zero Tolerance a lot of air time - especially over the past year. So I actually had to pause and think when my pre-order for the 0620CF popped into my inbox. I try to feature a variety of knives from diff ... continue reading
- Zero Tolerance 0562 cf Review
Updated: 05/30/2016 By this point we have seen quite a few of Hinderer / KAI collabs hit the market, and I have covered them extensively on the blog. We started with the heavily built 0550, moved to the critically ac ... continue reading
- Zero Tolerance 0801 Review
Updated: 11/29/2015 Titanium framelock flippers. Are we sick of them yet? No? Great, because I've got another titanium framelock flipper review for you today. Given the rapid influx of titanium framelock flippers on ... continue reading
- Zero Tolerance 0454 Review
Updated: 11/29/2015 Every so often as a knife collector I have had my expectations taken up a notch. For purposes of this introduction I'll call them "game changing blades." Making the jump from a $25 knife to a $65 ... continue reading
- Zero Tolerance 0566 Review
Last Updated: September 22,2017 I have recently been making regular appearances on the GearGeeksLive podcast with Tony and Andrew. Tony and I recently had Thomas Welk from KAI (Kershaw/Zero Tolerance) on the air for ... continue reading
- Zero Tolerance 0560 Review
Finally! A Zero Tolerance 0560 review. It feels like forever ago since the 560 was first announced at the 2011 BLADE Show. Since then I have heard the rumors, ogled the pre-production photos, and even caught a glimpse ... continue reading
- Zero Tolerance 0350 Review
Last Updated: November 22, 2016 My Zero Tolerance 0300 got a lot of looks when I carried it around. At over 9" long and with a weight of 8.6 ounces, it definitely raised some eyebrows. The excellent S30V blade was a ... continue reading
- Zero Tolerance 0550 and 0551 Review
Today I am taking a look at the Zero Tolerance 0550, a special collaboration between ZT and Rick Hinderer of Hinderer Knives. Rick has been making knives and self defense weapons for over 20 years. He started out spe ... continue reading
- Zero Tolerance 0300 Review
When Zero Tolerance first came on the scene the 0300 is one of their knives that really caught my eye. The graceful curves reminded me of some deep sea mammal while the construction reminded me of a semi truck. So I w ... continue reading
Zero Tolerance Knives
Zero Tolerance (ZT) has only recently appeared on the knife scene. I want to say this line is just a couple years old, but they have already made a big impression on the knife world. ZT partnered up early with famed designer Ken Onion to come up with some wicked designs. Ken has since moved on to CRKT, so it will be interesting to see what direction ZT goes into.
My guess is whatever Zero Tolerance does, they will do great. They have recently done some collaborations with another knife industry legend, Rick Hinderer of Hinderer knives. Between their collaborations with Rick Hinderer and Ken Onion, Zero Tolerance is coming out with some seriously heavy duty folders. I love the thick framelocks and ultra-high end steels ZT keeps using. This is definitely a brand to watch, and I will be doing many more ZT reviews in the future.
Zero Tolerance is also a proud partner with the Paralyzed Veterans of America (PVA). ZT donates a portion of the proceeds from every sale of a ZT knife to the PVA. This is super cool in my book and makes purchasing a Zero Tolerance blade just a little more rewarding – they couldn’t have picked a more worthy cause.
