Customer Reviews

Mike J. on Jun 14, 2016

This ZT is wicked. The design and size were the biggest selling points for me as I wanted a Sinkevich in a smaller form factor. The carbon fibre is nice and has the slightest of texture. The green pillars are a very nice attribute. The action is super smooth and has no issues opening. Opens with definitive authority and is very easy to close one handed. The bearings used are so smooth that the blade has a tendency to want to bite just from the smallest of a flick to put away the blade so watch the fingers. The lock up is rock solid and there is zero movement. Blade centering is spot on. Would buy again if I ever lost this.

Didn't think I would like it this much...
Matt C. on Jun 30, 2019

So I've had this knife for about a year now. When I first got it I was looking for a light weight EDC with a classy look. I love ZT so i went with this one. Despite what the reviews said I wasn't sure I was gonna like the knife that much. I tend to lean towards knives with thicker blades, but as soon as i got this knife I knew I had a new EDC favorite. I've carried this knife almost everyday for the year I've had it and I've never had to sharpen it. This knife is a total beast! Especially considering the weight and size. If you don't have one get it. The carbon fiber is super nice and the action is smooth as butter. It can hold an edge like crazy and fits in the pocket amazingly. Point is, get one!

My current favorite
Alejandro R. on Sep 5, 2019

This knife for me was love at first flip. Blade flies out with minimal force. This blade also looks very classy, but as a ZT can handle working hard.

Small but effective
James D. on Nov 27, 2018

This knife is so light, I actually thought they had shipped me an empty box (also because the standard ZT box was five times too big for this knife). Overall I agree with everthing said in other reviews. It's a great knife to have in your pocket and forget about, to tackle the basic daily tasks. The edge out of the box was very good but not quite excellent, and the thin blade stock makes it ideal for cutting through denser media (e.g., thick cardboard). My only gripes are the backspacers, which are a weird shape and I'll be replacing, and the action on closing the knife. As you bring the blade down it will catch and stop on the detent unless you keep the frame lock pushed aside until the flipper hits your thumbnail. Not a big deal, but something I haven't experienced to this degree with any other flipper. It just requires a little attention to technique.

It's a 10!
Craig T. on Aug 26, 2020

Perfect size and weight for everyday carry. Great materials and action.

Great edc
Samuel R. on Jan 5, 2018

Pros: •super smooth action •comes sharp enough to shave from the factory. •really comfortable. •nice to carry because its small and light. Cons: •may be a little too small

Awesome EDC
Glen E. on Aug 24, 2018

Just got this delivered today on national knife day. Action is amazing and it's really the perfect size for EDC. Very excellent knife!

Feels like a custom
Michael D. on Jan 5, 2018

The fit and finish on my example was perfect. The carbon fiber looks great, and the DLC is shockingly durable. The knife flies open without fail, and drops closed. The blade just cuts and cuts. ZT nailed it with this one.

Outstanding flipper
Michael A. on Jan 24, 2018

My first blade from zt and quite frankly it has blown me away. The titanium and cf handle scales look and feel amazing in hand, the weight of the knife is extremely light which adds to how sleek it is. The green anodized aluminium spacers add a nice amount of contrast to the black blade and handle. The action on this knife is buttery smooth, this will be my edc for most of 2018.

Perfect gentlemen’s knife!
Reese D. on Aug 24, 2018

This knife is my go to “dress knife”. It is so small in the pocket, but yet you get a huge blade on bearings that comes out as if it were on glass. Thanks Blade HQ

My !st ZT: My !st $200 Knife!
William M. on Dec 10, 2020

I never intended this knife to become my EDC. I bought it for its name, history, reputation, looks, etc., as an upscale addition to my extensive collection. But guess what? It climbs into my pocket everyday without me even noticing! I may have to buy a second just to have a pristine example in my collection! This one will continue to have its work cut out for it!

Great EDC
Alex w. on Aug 24, 2018

Loved this knife so much I bought it twice when I sadly lost the first one!

Fires like a dream
Han L. on Jan 19, 2018

This blade fires every single time. The closing action is also smooth like butter. Construction is solid just like every ZT. The blade stays dead centered even after substantial use. This is my work horse. When I'm not certain about the situation I'm getting into on that day, I always put this knife in my pocket. The only improvement for me would be an OEM deep-carry clip.

Dan W. on Jan 19, 2018

Love this knife got it for my birthday great knife in every way possible smooth action razor sharp ecstatic are great very light way! Great price for a great knife!

Just get one!
Scott S. on Mar 3, 2019

Amazing knife! Carbon Fiber and titanium scales. S35VN steel (good enough). The smooth action is incredible. The blade has a low-ish profile, perfect for EDC. Wish it came partially serrated

A sexy beast!
Joseph M. on Mar 14, 2019

This knife leaves me speechless. It’s so lightweight, great action, and it’s freaking sexy! Great steel too.

great every day
Shawn P. on Apr 28, 2020

04/01/2017 was the date i ordered this knife off this site. this was my first "expensive knife" and no matter how many i buy this is still the one that ends up in my pocket 9 times out of 10. its been lost twice, stolen once, used and abused still great, other than some clear damage to the finish on the blade after years of abuse. this knife holds a great edge still. light in the pocket. still opens smooth and fast. i only ever have had to work on one thing, other than sharpening it on occasion, i did some damage to the pocket clip at some point some how and had to remove it and bend it back to proper shape so it didn't sit loose on my pocket. great knife has never let me down. if you can afford it this is it. if you can't. save up and get it.

Buy it before it Doubles in Price
Neida R. on Dec 2, 2016

Zero Tolerance/Kershaw owned by Kai USA Ltd. Has a reputation for ending production of knives. Not saying this is a new Kershaw Tilt. But it reminds me of it. #1. If it was $280 its still sell #2. As others have said This is a new 2016 Paramilitary 2 challenger. #3. Buy it if you can find it they will be sold Out til Mid 2017 soon. #4. Don't be shocked if it goes out of production and its $400 soon. #5. Show me another $180 S35VN Carbon Fiber knife at this Price point ?

This knife is incredible!
Dylan P. on Aug 24, 2018

I have both the carbon fiber and the titanium versions of this knife, and the steel and the quality/construction is second to none!

Awesome EDC Addition!
Ben W. on May 18, 2018

I've had this knife for about 2 months now and it has quickly ranked itself higher than 95% of my other edc knives. The blade came perfectly centered and the fit and finish is superb. The design and ergonomics are awesome...and the action is extremely smooth...Like fidget spinner smooth. Found myself actively searching for the knife to flip while watching tv, working, even while driving..(not recommended). I will say that I wish the knife was a little bigger, as I have larger hands. This of course is not any fault of the knife, just personal preference. However, I will say that although it's a little small for my hands, it's so ergonomic and lightweight that I'm able to overlook the snug fit and still use it on a daily basis. I was a little apprehensive about the coated blade but it's held up very well so far. If you're even considering this knife, get it! It's a good value for the price considering materials, fit and finish, and overall design.

Awesome flipper
Jaret D. on Jan 26, 2018

Received this knife as a Christmas gift and couldn't be more pleased. I like that it's not a typical ZT (like my 0920). It just disappears in the pocket. Sharp out of the box and action like butter.

It's great
Anthony M. on Mar 14, 2019

It's nice for EDC and lightweight

My favorite small edc
Jon H. on Jan 5, 2018

I can't say enough about this awesome little knife. The KVT ball bearing pivot is as smooth as silk. Flips with VERY little effort. Locks up like a vault. The S35 blade holds an edge for a long time and sharpens up easily. Great knife for edc and light camp chores. Thanks ZT for a great knife.

Perfect EDC for me
Stephen G. on Dec 8, 2019

I own a number of ZT knives but this one fits the sweet spot for me. Super light, and i love the all black. No surprise with the high quality and great, razor sharp blade. This will replace this knive's big bother as my EDC. Always nice to have choices, God bless the USA

Great knife
Chad B. on Jan 6, 2018

With the carbon fiber and the size the knife feels like it disappears in your pocket! The action is smooth with great fit and finish. An amazing knife.

Great EDC
Jacob S. on Jan 7, 2018

Addictive flipping action, perfect for EDC! Just a great all around knife!

First "Expensive" Knife
Michael H. on Feb 20, 2020

I have about 12 knives in my collection so far. I bought this ZT because it stands out as almost uncharacteristicly small and thin for what ZT has been known for in their past. It is a great execution of a nearly perfect action. I haven't had to tune it, oil it, nor sharpen it. Now I can see and feel the justification for a $200 knife. So I'm wondering what happens at $350? :)

Nick C. on Mar 4, 2019

Better than I even expect. The action on the knife is beautiful!

Classy EDC
Dan E. on Jun 21, 2019

This is sweet. The real cf scale and the green back spacers are a beautiful combo. My only gripe is the detent on the flipper is pretty strong so you really gotta overkill the press to get it to flip out. My office EDC. I love the s35vn and want to get more knives with it after using this blade. Wouldn't take it out with me. Just a touch too small, but that makes it a perfect light weight and sleek model for the office. Pocket clip is really nice and not too strong either.

So dang nice!
James F. on Sep 12, 2019

I own a lot of ZTs, some Benchmades and a few Spydercos. But this is the first knife that's motivated me to write a review. Love this little flipper! It is so light, so snappy and the appearance is so refined ... this knife makes me happy. My most frequent EDC is the BM 940 and I'd say this may be it's rival. It carries similar to the 940 with a little less weight, a little less blade and a little less handle but it's better looking IMHO. As a matter of perspective, this is my smallest knife. (I don't like blades smaller than 3.25.) If you're similarly inclined, you might find this to be your favorite "little" knife.

The action is perfect
Izzy F. on Jul 11, 2019

I love the action on this knife. It is smooth and make a beautiful sound. Solid materials and a great design make for a sold knife. This is also a slim knife out of ZT is a beautiful thing.

Jack S. on Jan 5, 2018

This knife is great the detent is perfect making the knife very quick along with the bearings it pivots on. The carbon fiber and titanium frame lock make this knife extremeley light. I was surprised to find it was comparable in blade length and size to my benchmade 940 because of the weight difference. Overall this knife has been great and a favorite since I’ve had it.

Awesome Knife!
Andrew F. on Aug 31, 2020

This is a perfect knife: Extremely well made; Perfect size; Light weight and carries well. Zero Tolerance knives are in a class of their own and the best knives on the market at this price range.

Zach L. on Apr 23, 2016

Always wanted a ZT but always spent my money on Benchmade or Spyderco. After my girlfriend bought this for me for my birthday I wish I would have bought this knife forever ago! Super light and extremely smooth opening. Extremely sharp out of box and the green bushings look great when in pocket.

awsome knife
Kenneth C. on Apr 18, 2020

knife is awsome and the 2 day delivery in the mist of covd19 pandemic is unheard of keep up the good work.would order again

Mark b. on Feb 11, 2020

This is my new EDC. I am a devoted benchmade man and it took quite a bit to sway to get this knife. WOW!!! This knife is not only masterfully designed and crafted but also a beauty to look at. A the action is slick as snot. It came sharpened razor sharp. I get a lot of people who ask me about this knife. The only thing I had to do was order a deep carry clip. Other than that it's a marvelous knife.

Excellent light carry
David H. on Jan 6, 2018

This knife feels so light and small when folded but man the blade length makes full use of the space available, you would never guess a more than 3” blade was inside! This thing is classy with the carbon fiber and green barrel spacers. I have no problem flipping this knife, just make sure the pocket clip isn’t resting on the lock bar. It happened to mine once, so just untighten the screws on the clip, shift it over so that the clip is resting on the frame, and then re tighten the screws: problem solved. This is the smoothest flipping ZT I have, great little folder!

Favorite carry
Max d. on Mar 16, 2019

This knife is amazing light and very ergonomic

Gentlemen Folder Sinkevich CF
William B. on Aug 8, 2020

I have had a ZT before. It was a collaborative between ZT and Emerson. Certainly a lot bigger than this one. What they have in common is the great build quality, smooth deployment and quality steel. The Sinkevich is a gentlemen folder or exec if you will. It is light for a ZT. Fits in my pocket with clip and I hardly notice it. Unlike my Emerson ZT. Blade is certainly long enough to get the office job done as well as other "tasks." The S35VN steel is quality. The carbon fiber scales are cool and reflect a bit giving the knife a stealth look.With lifetime sharpening. Blade HQ has excellent service and fast shipping times. Pick it up. You won't be disappointed.

spyderco f. on Jan 22, 2018

This knife is simply superb. Fantastic action, great looks. It is well worth the price. This knife has an action that rivals some customs. You cannot go wrong with this awesome blade!

Best EDC knife!!
Ronni B. on Feb 19, 2018

Came down to the 0450CF and the benchmade 940-2. I picked the 0450 because of the light weight design, blade material, and the biggest deal breaker for me was the action. The action is by far better than the 940 and i prefer the flipper over the thumb stud. Only wish i have is they make more color options and accessories for this knife. would love to see this knife in the color scheme of the 0452 with green barrels on it. I would buy it in a heart beat.

Awesome Knife
Thomas F. on Oct 12, 2018

I bought this knife a month ago and ive have had this little guy in my pocket ever since. Great steel, very smooth, great price for the premium materials and the detent is perfect. If I had to give one complaint about this knife it would be that the ergonomics aren't that great for large hands.

Perfect EDC blade
ryan d. on Sep 23, 2017

Just what I was looking for! Most ZT knives are simply too big for everyday carry. I wanted something light, yet strong and that could still get the job done. This knife is the answer. Great ergos, fits perfectly in my pocket and weighs almost nothing! 10/10

Paul S. on Sep 23, 2021

The moment i put this knife in my hands i had to have it. Typical ZT build, action and quality. Lightweight and razor sharp. One of ZT's best models in my opinion.

super sleek carry
Ryan L. on Jul 24, 2020

This is my first Zero tolerance and I doubt it will be the last. It has the smoothest action of any knife that I own while also maintaining a tight lock-up. The bearing still has some spots in it such that I wouldn't classify it as "butter", but I'm certain it will break into that point given time and my pension for playing with knives in front of the TV. My only complaint and the reason for 4 stars is that every other premium knife I have bought, spyderco, benchmade, etc have come shaving sharp out of the box. Given the quality of the steel I expected that to be the case with this knife but it was not.

Amazing quality
sean b. on Feb 8, 2016

This knife is as sweet as the other 0450, only lighter. Flips open fast as lightning. It's so smooth and slick, when its open you check for blade play, and there is none. The lockbar insert makes closing a breeze. The carbon fiber is not too shiny, not too dull. Nice. It actually looks good with the green spacers. Blade is great. Top quality. The printing of the serial number and everything is crisp and defined. Would buy again.

First ZT
J. T. on Jul 14, 2021

Initially I was very disappointed in the action. It just felt like something was grinding. And, while very sharp out of the box, I knew I could do better. But first, that grinding needed to be addressed or else it wasn’t going to be around long enough to sharpen. My look-see after opening it up for inspection revealed absolutely ZERO lubrication on the pivot and detention ball. A touch of pivot lube where needed and reassembly and now it’s like butter! I’ve never had a knife open so smoothly! S35 should be all you need to know for sharp, and it is, indeed! My final thought, at this price, I shouldn’t need to pull out my tools first, but I’m glad I didn’t just send it back with an angry note. I did add a deep carry clip! Happily, it’s now my EDC and it DOES NOT get loaned, to anyone, for any reason.

Best $180
Philip y. on Jan 5, 2018

For anyone looking for a smaller edc and is willing to drop $180 on a knife, I dont know of any better knife. This one checks all the boxes. Value, materials, fit and finish, ergos and design are all very good. Best part of this knife is the deployment, it is quick and very satisfying. Many people who I've shown this knife to, think its assisted. Really wish they would make the cf with a satin blade more readily availiable

Smoothest flipper under $200
Crystal A. on Jan 19, 2018

This guy really surprised me. I was so used to my shiro NeOn and had a sort of snobbish attitude toward ZT. I picked this guy up and was blown away. It has a great detent and fall shut action. It is easy to maintain and the perfect size for EDC.

Would Buy Again
Sean V. on Feb 25, 2016

An excellent knife. Blade steel, profile, and finish are all top notch. Titanium handle is likewise well built. The carbon fiber front scale is smooth, but with slight texturing- has to be felt to truly understand, but elegant and functional at the same time. No side-to-side or up-and-down blade play whatsoever. Locks up smooth, about 30% lock engagement- plenty of room to wear into. No slipping or disengagement of lock, even with spine strikes. Fasteners all tight, and thread locked. The detent is strong, but with the flipper and ball bearing pivot, the blade stays shut when you want it to, and deploys fast, and with authority. The force necessary to disengage the detent is sufficient to fully open the blade; try as I might, I couldn't manage to "short stroke" the opening- it snapped into place every time. Open handle, with green barrel standoffs, somewhere between lime and emerald green. A nice touch. Two-screw vertical pocket clip, tip up L/R only. Only one thing stops it from being five stars: the blade is slightly off-center in the closed position. Not much, only a millimeter or so, but enough to be noticeable. Even with all fasteners loosened and carefully re-tightened, it's still there. the fit and finish is otherwise excellent, and it slight off center does affect operation whatsoever. Would recommend this nice; an excellent EDC/dress knife, which will also work defensively in a pinch. Looks good, feels good, and works well. Personal preference, maybe a deep carry pocket clip would be a nice addition.

Great choice for edc
Joel N. on Jun 12, 2018

Awesome light weight and compact carry knife that can get stuff done. Carbon fiber scale looks amazing and the action is buttery smooth right out the box. Only issues are that the dlc coating on the clip, blade and lock side scale aren't great and the handle felt a little small for larger sized hands. Other than those little gripes, the knife performs amazingly and I'd definitely would recommend picking one up.

Good, not great for a lefty
Leischen N. on Feb 25, 2018

First BHQ is top notch! Fair prices, fast shipping and excellent customer service. Second, Love the ZT Line of Knives, own six! The 0450 is built with high end materials and well built as are all ZT Knives. The 0450 is not a good piece for a left handed person. When the clip is mounted for left hand tip up, your thumb falls naturally against the lock bar. This significantly impacts deployment. The 0450 is very light and feels good in the hand once deployed. However it does not feel substantial. As a result it feels like an $80 Knife rather than $180 knife. An 0350 looks and feels like a lot more knife for less money. When deploying the blade right handed it is very fast and locks up solid. A little buyer remorse from a lefty 🙁

Charles M. on Jun 29, 2017

Sent one of these back where I purchased it... it was extremely difficult to open. The one that replaced it was just as difficult. Of all my flippers this is hands-down the hardest to open. It certainly doesn't "flip." I can open it, but it all but tears my rotator snapping my arm to do so. Kept #2, but I don't carry it. Looks good in the display case though.

It’s scratched badly
Jeremy g. on May 27, 2022

I really love the knife. The problem is the carbon fiber came with a deep scratch 3/4 of an inch long that really stands out and several smaller scratches all over it. Very disappointed.
