  • Black finished recurve drop point blade made of S30V steel.
  • Flipper and dual thumb stud spring assisted opening.
  • Textured black G-10 handle scales.

Customer Reviews

This'll put hair on your chest...
Michael O. on Mar 20, 2020

If you like the feel of an Emerson knife in your hand, you'll love this knife. This is my 17th ZT knife and it's the only one that if I were blindfolded, and someone put it in my hand with the knife already opened, I'd swear it was an Emerson. I'm kind of on the fence with SpeedSafe, but it works very well with this beast of a knife. At this sale price, the ZT 0350 is a steal. If you like the feel of a substantial knife, buy it now.

Fantastic Knife
Scott R. on Mar 7, 2019

This is my first ZT and not my last these knives are the Sig sauer or H&K of knifes imo!

Present for dad
Eric W. on Feb 22, 2019

Bought this for my dad who is retired navy and grew up in northern Michigan spending most of his time in the wilderness, and he loves it. He loves the assisted aspect of it and it’s hard use type blade. He said it’s a little heavy in the pocket but thin enough you forget it’s there. The black blade coating gets marked up fairly easily but it’s just superficial. Can be wiped off with a damp cloth. I’ll be picking myself up one sooner than later.

Built Solid
DJ W. on May 9, 2018

This knife has become my only EDC since I bought it. To some people it will be to heavy, for EDC, but if you give it a chance I promise you'll get used to it. It came razor sharp. Opens fast and locks hard. Its a little noisy in deployment, nothing like a few benchmade knives come across that have a quiet like deployment. I've sliced through 1/2in cardboard with this knife before with ease. I've slid across asphalt on the pocket clip after a fall and it's only suffered small scratches. This knife still has no blade play by the way. Its almost like a fixed blade guys. This knife gets used in my kitchen often so its washed often as well. It has yet to show any rust. The only flaw in this knifes' design is the torsion bar I've had them shear in half before. KAI will replace them though at no cost so I see no problem as long as ZT keeps producing this model.

rugged yet refined!
Michael R. on Jan 25, 2018

This knife is ZT at its best! Rugged and great feel in the hand. Great G10, and the coated S30V blade is perfect. Blacked out hardware is perfect. Love the speedsafe opening. Buy this Knife!!!

Mini grip review. Zt 0350
Jake c. on Jan 21, 2018

Easily the best knife I own , perfect for every job imaginable and amazing to look at and play with , gives you so much confidence to carry a knife like this. Worth every penny .

Love it
Scott B. on Jan 13, 2018

I love this knife. It’s tough as nails. This is in my pocket whenever there is hard work to be done. It’s been in the dirt, rain, mud, and snow. Its comfortable and grippy in hand. The blade opens easily, holds and edge and is easy to keep sharp. I bought this knife when it first came out, I don’t think I spent this much when I bought it though. This is a working mans knife, not a fashion or status symbol. Unfortunately I feel ZT has turned into just that, a knife to show how much you’re willing to spend on a fancy, well made knife. I wish they’d have stuck with the somewhat affordable knife for the people who need a quality knife made with quality materials and who use them to their full potential. I like their newer knives, don’t get me wrong, they are top notch, but most are out of my price range these days.

Solid knife
Jon H. on Jan 5, 2018

The 0350 is a solid knife. The assisted opening is fast. Lock up is solid. The S30V blade takes a super sharp edge and holds it for a long time. Although I typically prefer a slightly larger knife. This knife is great for edc and is stout enough to handle heavy chores.

My first ZT knife.
ALAN S. on Aug 13, 2020

My first impression is that this is a cool knife. It has the best flick sound of any knife I own. The G10 has a good feel and the larger blade is awesome. I am an old geyser so I didn't get the Zebra blade. I wish I had. My only complaint is that the lock is too small. At this point I have to use both hands to get it closed. Hopefully I will figure out how to unlock it in a better way.

Built like a Tank
Shane C. on Mar 4, 2019

This knife is built like a tank and is a very good knife. But it does live up to it's ZT name because it is a chunky knife. It is a great everyday carry if you do hard work and need something to depend on.

Very disappointing
JEFF W. on Apr 23, 2022

This one is going back. Far from being assisted opening, it takes two hands to open. Yeah, maybe I could tweak it a little to get it to work better, but I shouldn’t have to for the price of the knife. ZT’s reputation is way overblown as far as I am concerned. This was my first ZT and can’t see buying another when there are other and better options out there in the same price range. Two stars only because the parts appear well manufactured.
