Zero Tolerance Knives

Zero Tolerance Knives

Zero Tolerance is a series of knives from Kershaw 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 like myself love.

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 including some of their best models:

  • Zero Tolerance 0620 Review Zero Tolerance 0620

    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 BladeHQ pre-order for the 0620 popped into my inbox. I try to feature a variety of knives fro ... continue reading

    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 knife was one such mo ... continue reading

    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 force to be reckoned with, and I ... continue reading

    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. Since Ken has since moved on to CRKT, it will be interesting to see what direction ZT goes into.

My guess is whatever direction ZT 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.

    I recently picked up a ZT 0301 and can’t say enough good things about this knife. I’ve carried an Emerson for the last twenty years, and as much as I still love my Emerson blades, I’m now a die hard ZT fan and have upgraded my fixed blades to ZT’s as well. I’m a law enforcement officer and combatives instructor with a heavy emphasis on edged weapons, and this knife is ideal for both heavy use and self-defense purposes. Well done by the ZT team, I recommend your products to everyone.
