High-Performance Steel

Featuring superior toughness, excellent hardness and great wear resistance, S30V steel has high amounts of carbon and vanadium to provide superior edge-holding and abrasion resistance. S30V steel also offers users great corrosion resistance and improved ductility. With a chemical composition to prove it, S30V is a premium, high-performing steel great for everyday use.

Coated Blades

Diamond-Like Carbon (DLC) coating is often even tougher than the blade steel underneath it. DLC-coated blades offer extra hardness, high corrosion resistance, excellent wear resistance and a low friction coefficient so particles do not easily attach to the blade. DLC coatings display properties similar to a natural diamond that add beauty and attractive shine.

Fast Deployment

Using a torsion bar to move the blade out of the handle, Kershaw’s revolutionary SpeedSafe Assisted Opening system enables smooth, secure, fast one-handed blade deployment. Apply manual pressure to the flipper or thumb stud with a light push or pull back to overcome resistance of the torsion bar, and the blade opens smoothly and locks into place for confident handling without premature closure.

Secure Locking System

With two steel plates, or liners, on the inside of each handle scale, the liner locking system safely secures the blade open and prevents unwanted blade closure. The lockbar butts up against the blade’s backend to prevent closure, and angles or is bent towards the blade tang creating a bias locked position. Apply manual force to move the lockbar to the side and fold the blade back into the handle.

Exceptional Quality

One-Handed

G-10

Clip

Knives with SpeedSafe open have two options for one-handed blade deployment. To activate the smooth, instant open, user can push a thumbstud or press a flipper. The flipper on SpeedSafe assisted knives is easy to operate by both left- and right-handed users. And, once blade swings open and locks into place, flipper either disappears for aesthetics or remains visible for added finger protection.

G-10 is a laminate composite, epoxy-filled woven glass fiber that is extremely stable, very lightweight, tough, hard, strong and unaffected by temperature changes. G-10 handles can be decoratively tinted, ground or polished in checkering, lines or other patterns to add texture. Excellent for heavy-use, tactical or utility knives, G-10 can be machined into shape providing a stronger grip.

Kershaw designs pocketclips to fit specific knives according to their weight, intended end use, size, style and hardware. Some knives have multiple carry options, others are more streamlined. The 4-position pocketclip allows tip-up or tip-down carry on both the right and left sides, providing users the most versatility. Proper use of the pocketclip promotes safety and efficiency while using knife.

Product Description

Product Description

This Zero Tolerance pocket knife is smaller and lighter than its predecessor yet packs the features users prefer for everyday carry. The 0350ST model features partial serration at the base of the knife, enabling it to cut various types of cord and other fibrous materials with ease. Featuring patented SpeedSafe technology, blade deployment is quick and easy with the ambidextrous flipper. The 3.25-inch S30V stainless steel blade is tough, holds an edge, and is resistant to wear and corrosion. A matte-black non-reflective, Tungsten DLC (Diamond-Like Carbon) coating offers additional blade hardness and reduces friction. The handle features a textured G-10 scale for excellent grip and mechanical strength, even in the roughest conditions. A sturdy locking liner secures the blade open during use, and a pre-drilled lanyard hole provides carrying versatility, while ZT’s Quad-mount system offers adjustability in any of four ways: tip-up, tip-down, on the left side, or the right.

Amazon.com

The Zero Tolerance 0350st is 10% smaller and lighter than the classic 0300, with a new partially serrated blade for added cutting versatility, while maintaining the cutting and piercing power that made the original such a popular model. It's equipped with SpeedSafe manual assist for easy one-handed opening, meaning you can easily deploy the blade while wearing tactical gloves by using the large, ambidextrous thumb stud or blade protrusion. The stout, sharp blade is made of S30V stainless steel with a rugged Tungsten DLC (Diamond-like Carbon) coating. Textured, matte-black G-10 scales on the synthetic handle provide an extra-secure grip, and the knife comes complete with a quad mounting system for tip-up, tip-down, left-, or right-handed clip carry.

One knife to rule them all
5 Stars
One knife to rule them all
As of right now (and since I bought it) this is my absolute favorite edc knife. Put it through some pretty good wear and tear in the woods and in the city so it's seen both sides. I've had my fair share of CRKTs, Browning, Kershaw, and even benchmades but this tops them all in my book. Not saying the other companies don't make amazing knives, I've just never found a model that has a G10 handle to prevent slippage (PNW weather), S30V blade (toughest knife blade steel within a reasonable price range), thumb and finger release with lightning fast springs, serrations, and comes in black all within a fraction of the competition's cost or a custom shop blade. This is a meaty blade, definitely built for potential survival situations so keep that in mind if you have smaller hands. With more material comes a higher weight too, so all things to keep in mind. I'm 5'10"-5'11" with average medium sized hands and it's not big for me by any means so hopefully that puts it into perspective. Anyways, this thing is incredible. Can't recommend it enough.

5.0 out of 5 stars Great value for a feature-packed knife
Reviewed in the United States on May 9, 2015
Verified Purchase
This knife represents an outstanding value for the features provided. Speedsafe opening, S30v blade material, serrated and Tungsten DLC coating, and lifetime warranty all for $140 - wow! Extremely sharp out of the box.

PROS:
- S30v steel used for the blade is widely regarded as the best in the business
- Speedsafe can be activated via thumb stud on blade or a protrusion milled into the back of the blade that sticks out from the back of the handle when closed. This allows the blade to be opened one-handed with either the user's thumb or index finger
- Nice tight belt clip. I wear my pocketknives on the inside of my front pocket. Other knives I've tried tend to fall into my pocket due to the clip being too loose. Haven't had that problem with this knife at all.
- Size is perfect for me. Large enough for a positive grip, but small enough to not feel bulky in my pocket. Blade length large enough to be useful without exceeding maximum length laws in most jurisdictions.

CONS:
- Knife was pretty tight when I got it. While this gives an overall impression of quality, in practice I had a hard time fully extending the blade using the thumb stud at first. You may want to apply some lube or just continually deploy it for awhile until it begins to loosen up a bit. The locking mechanism in the handle was similarly stiff, making the act of closing the blade a precarious endeavor the first few times I did it.

All in all, this is my favorite knife (previously owned a couple Benchmades and a Kershaw). It exudes very high quality and is a tremendous value for the money. I expect it will last right around forever. I would highly recommend this knife to anyone.

5.0 out of 5 stars A tank of a Folder!
Reviewed in the United States on February 12, 2014
Verified Purchase
Bought this knife for EDC and for hiking, camping, etc. I've had it for a couple months now and I can't say enough good things about it. For just over $100, you will be hard pressed to find a better quality knife. Heck, double the price and the same holds true. The build qaulity is outstanding and I can see it lasting for decades. The blade is sharp right out of the box and seems to hold an edge very well. Since purchase, I sharpened it with my Spyderco Sharpmaker and it's razor sharp. The finish on the balde is showing a little wear but that just gives it character. The assisted opening works great. I've always used the blade posts on other knives to open the blade but now really like the assisted open on this knife. I will say the blade posts are pretty much useless on this knife. I have a lot of different knives like Boker, Benchmade, Spyderco, Gerber and I can say this is the best folder I have now. I think I might buy the same knife with the standard blade as well.

Cons:
* Heavy - But, this thing is built to take some abuse. I'm a pretty big guy and the weight is fine with me for an EDC.
* Thumb posts are useless - But, the assisted open system is outstanding
* The clip is really tight - almost to tight

Pros:
* Made in the USA
* Sharp out of the box
* Build Quality - built like a tank to take abuse. Just outstanding.
* Easy to open and close
* Good locking system
* Price - Probably won't find a more durable better knife at this price point or even double the price point

4.0 out of 5 stars Kershaw Fan
Reviewed in the United States on February 21, 2012

Firstly I am a Kershaw fan. I have owned and carried a Kershaw Blackout speed safe with serrated blade for many years now. The Blackout is an excellent knife for everyday carry. It's price, quality, function, reliability, all top value. I even bought a spare in case I lose my original. That one is still pristine. But, the Blackout is a bit light and flexy so I am always looking for something better. So, with that in mind, I purchased the Kershaw Ken Onion Tactical Blur Folding Knife with Speed Safe. Another great knife, great action but a bit "edgy". The Tactical Blur is a very fine knife, so much so I almost hate to use it as I don't want to damage it. Plus the handle is a bit rough in my pocket and the thumb studs have very sharp edges, had to file em smooth so they did not catch in my pocket, so I still carry my Blackout everyday.

I became enamored of the ZT G10 so I bought that one too. A bit pricey but once again an amazing knife. Much stiffer than the Blackout but a bit bulky. Opening with the thumb stud is a bit stiff as it too close behind the speed safe "cam", but the knife opens with zero effort with the "flipper". Either way you can easy master the action. I have large hands but still find that the G10 scales, while grippy, are a bit rough and bulky. I also might suggest Kershaw use larger diameter washers at the blade pivot to increase stiffness further without too much of a penalty in opening friction, and move the end of the center spacer closer to the pivot to take some more of the load off of the blade pivot to make it even easier to open. Overall I give the ZT G10 with speed safe and serrated blade an 8 out of 10. I would love to see Kershaw build a knife with the smoothness and ease of carry of the Blackout with the beef, stiffness, action, and features like the "flipper" and the re-positionable pocket clip of the Tactical Blur and the ZT G10. Yeah, talkin to you Ken Onion. Watcha got?

While you are at it check out my new book. Yeah, I golf too.

5.0 out of 5 stars Sehr solider "tactical" folder.
Reviewed in Germany on January 15, 2017
Verified Purchase
Habe das ZT-0350ST für einen Freund bestellt. Natürlich habe ich es mir vorher angesehen und ausprobiert.

Die G10-Griffschalen sind sehr griffig aber nicht sehr aggressiv gekörnt. Sehr angenehm in der Handhabung, aber nicht so rau, dass es einem die Hosentaschen aufwetzt. Bis auf das große "ZT-Logo" ist der mitgelieferte Clip sehr schön und funktioniert auch einwandfrei. Man kann diesen in allen vier Positionen anbringen. Also links, rechts, tip-up und tip-down. Die Klinge kam sehr schön zentriert ohne jegliches Klingenspiel. Als Klingenstahdl kommt S30V zum Einsatz, welcher sich durch hohe Korrosionsbeständigkeit und Schnitthaltigkeit auszeichnet. Etwas schwer zu schärfen, aber eigentlich ein sehr guter "Premium-Stahl". Da das ZT0350 mit einer "Recurve" in der Klinge daherkommt, sicher nichts für Anfänger unter den Messerschärfern.

Bei der Öffnung der Klinge kommt eine Federunterstützung zum Einsatz - also "assited opening". Das ist Geschmackssache und in manchen Ländern auch rechtlich relevant. Diese Feder kann beim ZT0350 allerdings sehr leicht ausgebaut werden, wenn man lieber einen manuellen Flipper hat. Dies ist vor allem Möglich, weil die Klinge im geschlossenen Zustand von einem "Detent ball" unter Spannung gehalten wird. Das ist nicht selbstverständlich, da bei vielen assited opening Flippern die Grundspannung der Klinge durch die Feder bestimmt wird.

Einziges Manko ist das wohl recht hohe Gewicht von ~160 gramm. Für ein Messer, das man täglich eingesteckt halt etwas schwer und auch sehr Hosentaschenfüllend. Dafür bekommt man einen "Taschenpanzer" mit minimalsten Toleranzen in bekannt hoher ZT-Qualität. Mit einem Kauf macht man hier bestimmt nicht viel falsch.
