A knife for life, the Zero Tolerance 0512

If I were asked to describe the ZT 0512 in one short sentence, it would be easy for me: this is the knife you use for a lifetime and pass along when your time is done.

I first heard about this model in an Oregon Gear Guy video about the CRK Umnumzaan, where he used the 0512 as a comparison piece. After watching, I spent a couple of days reviewing specs and anything else I could find. On a whim, I decided I wanted to get it in hand and see if it was something I’d actually be interested in.

My wife and I were out shopping for her new work shoes when we passed my local knife shop. We stopped in, and luckily they had a 0512 in the display. I asked to take a look, and the moment it hit my hand, I knew there was something different about it. It felt unlike any other ZT I had handled. A brief conversation later, a new box came out, my card got swiped, and I was on my way.

At the time, I was carrying a Kershaw Launch 22, which I still think is a phenomenal knife—but the 0512 just felt different. When we got home, the 22 went into the case, and the 0512 went into my pocket.

The first thing I noticed was the action. I’ve owned a lot of automatic knives, but this has the strongest deployment of any I’ve used. If you’re not paying attention, it can jump out of your hand. Lockup on the 3.45″ clip point CruWear blade is solid—nothing about it makes me feel like it’s going to fail under normal use. It’s not a knife you’re going to baton wood with, but at this point, we all know a fixed blade is the right tool for that anyway.

In-hand feel is excellent. Micarta has always been one of my favorite handle materials—it develops character over time, maintains grip when wet, and stays warmer in colder conditions than something like aluminum.

The blade shape itself is a strong all-around EDC profile. The clip point works well across most tasks, and CruWear gives you solid edge retention, even if it takes more effort to resharpen. The Cerakote finish will be hit or miss depending on the person. I like it—it adds corrosion resistance—but it will show wear. Personally, that doesn’t bother me. Wear tells a story. I use my gear, and I want it to look like it.

At 3.45″ long and 0.16″ thick, the blade might be a bit much for some people depending on local laws, but for me it’s right where I want it. It’s not the sliciest blade out there, but it’s durable enough to handle harder tasks, including things like fire prep.

The handle is large enough for a full grip, with rounded edges that prevent hot spots during extended use. The one exception is the pocket clip—its upswept edge can dig into your palm if your grip isn’t ideal. It’s not a frequent issue, but it’s worth mentioning.

The titanium non-show side scale has a smooth but slightly textured finish that still provides good grip. The button is well designed—slightly raised and easy to operate, even with gloves.

Price is always subjective. At $320, this isn’t cheap, but it’s not at the top end either. For what you get, I think it’s fair. If it were closer to $250, it would be an easy recommendation. At its current price, I’d call it a good buy.

Since this is my first review, I want to explain my rating system.
1 = Stay away
2 = Okay buy
3 = You won’t be disappointed
4 = Damn good
5 = Must buy

So where does the ZT 0512 land? For me, it’s a solid 4. It’s not perfect, but it’s a dependable tool that can handle just about anything you’d realistically ask of a folding knife. This will likely become my primary EDC.

I’m not here to tell you what to buy—just to share my experience. But I don’t think you’d be disappointed spending your money on this.

Final Note: I intentionally didn’t focus much on the automatic aspect. You need to understand your own local, state, and federal laws. I’m not a lawyer, and that responsibility falls on you.
