Zero Tolerance 0770CF Assisted Opening Flipper Folding Knife (3.25 Inch ELMAX Stonewash Plain Blade) Carbon Fiber Handle ZT
0770CF: Model 0770CF Assisted Opening Folding Knife Carbon Fiber
Zero Tolerance Knives
A NEW CARBON FIBER HANDLE MAKES THIS AN IMPRESSIVE EDC
The original award-winning Zero Tolerance 0777 is a very limited-run knife. Yet interest in it is high among blade aficionados. That's why Zero Tolerance is happy to announce a version of that award-winning knife--one that will be much more generally available. The 0770CF offers the style and performance of the award-winning 0777, but in a slightly smaller, streamlined version.
For ZT performance, the blade is ELMAX powdered steel, which provides the ability to take a razor edge, excellent edge retention, strength, and toughness. A stonewashed finish on the blade hides hard-use scratches and makes maintenance easier. The sweeping lines of the original 0777 are preserved in the lightweight carbon-fiber handle that fits securely in the hand. An inset liner lock in titanium secures the blade without adding unnecessary weight.
The 0770CF opens quickly and easily thanks to SpeedSafe assisted opening and the built-in flipper. Pocketclip and backspacer are machined titanium for lightweight strength. For a final touch of class ZT adds a handsome oversized pivot.

This knife is perfect for EDC, especially when you want to dress up or when wearing a suit and tie. The pocket clip is a deep carry clip that is perfect for discreet carry. It a beautiful well made American knife from ZT and I am really glad I added it to my collection.
Until the ZT0770 (hereinafter the 0770) most ZT's ranged from boat anchor to trade paperback in terms of their carry profile. They are great knives, built like vaults, but man are they big. The ZT560 was positively massive and the ZT350, their small knife, is giant too. This says nothing for the Bunyanesque ZT0200 (7.8 ounces! Ahoy Matey!). When Derrick sent me the 770 he prefaced it by saying it was one of his favorite knives. The minute its slim profile slipped out of the box I knew why. This is a ZT knife in EVERY SINGLE WAY--the materials, the fit and finish, and the design. But it is also a knife that regular folks in regular jobs can carry and use.
Hereis the product page. The Zero Tolerance ZT0770CF costs $180. There was an aluminum handled version, but that appears to have been discontinued. Hereis a written review. Hereis a video review (he either got an uber rare version or he got the steel wrong--its Elmax not M390). Here is a link to KnivesShipFree, where you can find the ZT0770CF, and all proceeds benefit the site when you purchase things through this link:
Here is my review sample (to be given away; I am trying a new set up for pictures, let me know what you think in the comments):
Here is my video overview:
Twitter Review Summary: THE ZT for non-sasquatches--an awesome EDC blade.
The angles and cuts on this knife, the things that give it its shape, are so cool looking. This is a knife that looks like a human muscle attached to the skeletal frame--taut, purposeful and poised. I love the handle shape and lines of the knife. Visual tension is here in spades.
But this isn't just a pretty knife, its a well designed one too.
Here is a size comparison:
The performance ratios are very good: blade:weight is 1.08 (thank you Mr. Carbon Fiber) and the blade:handle is .76, the same as a SOG Flash I. That last comparison is something I find stunning and testament to how great this knife is. This is easily in the same class as the Benchmade 940-1and the Spyderco Paramilitary 2--truly rarefied company in the production world.
Fit and Finish: 2
It fits the knife nicely and provides a bit of silver bling to match the flawless carbon fiber. The centering is superb and that is something given how thin this knife is and how thick the blade steel is--there is no room for error. The stonewashing is even and excellent. Everything is just great. I feel like a Motor Trend writer trying to find new ways to say that a Ferrari is fast. You get the point though--ZT is making some of the finest production knives in the world and the 0770 is no different.
As you can see the knife just nestles into my hand, with the flipper doing double duty as a finger guard. Its a great shape. One thing I would mention, not as a criticism so much, but as an explanation of a difference, is that the aluminum version, which was discontinued (probably because it was too much like the Mini Matrix) and the Microtech rip off, both had some sculpting to the handle and that did feel better. The CF, especially on the clip side, is slick. That's not to say the grip here is bad, its not, as the score tells you, but it could be better.
I originally bought a ZT0200 as my first ZT. Oh my god was that thing huge. It felt like I was carry a hand grenade in my pocket (the scale's texture helped convey that sensation in addition to the knife's portly dimensions). Fortunately I was able to exchange it for the diminutive (by comparison) ZT0350. The effect was immediate--that knife seemed manageable. But when I got it home I was struck by how it felt compared to other knives. It too was too big in the pocket. In the end every ZT has had the curse until now. The 0770 is just great in the pocket, truly superior. ZT now makes and EDC blade and the ZT0770 is it.
This my fourth or fifth knife with Elmax and it never once let me down. This is a great cutting steel and not hard to maintain. In the holiday season my knives get a real workout. I am still processing some firewood and I am also breaking down boxes like a fiend. Our extra tiny recycling can has been, perhaps, the best thing that could happen to my knife testing regime. The 0770's Elmax has been great. Perhaps all of the Elmax haters out there haven't had enough experience with the blade, but as my number of reviews approaches 250 items, I feel confident in saying that Elmax is one of the better steels on the market.
Blade Shape: 2
the difference is very good. I like the less aggro shape, perfect for EDC and I truly appreciate the loss of a recurve edge. The ZT350 was a beast to sharper, what with the hard S30V steel and the recurve. Thankfully, none of that exists here and the the 0770 was both easy to strop and sharpen.
The high grind is even and thin (VERY thin compared to other ZT knives). It is also very well done. The cutting bevel is wide allowing the knife to register well for use on sharpening stones and the like. I appreciated the true ricasso here as well. Not a single problem with the grind.
Deployment Method: 1
You can de-assist this knife, but the action is mediocre. I know that assisted openers sell well, but this is an enthusiast knife, priced at $180, so I don't know why they left it assisted. Enthusiasts do not like assisted knives. They just don't. If they did, there would be more assisted customs (I can't even think of any off the top of my head). This knife with a bearing pivot or good washers would be awesome. The flipper is a great shape and size, I just dislike assisted opening knives. In addition to that, the assist felt balky in some ways. It wasn't slow, it just seemed to engage at different places along the opening path at different times and for no real reason. If you like assists, ignore this complaint and go back to your collection of half-serrated knives you philistine. I kid, I kid...not really.
Retention Method: 2
Its the clip from the Cryoand it is one of my favorite production clips. I don't need over the top but it is done so well here I don't mind. It is also quite stable, long enough to lock the blade in place, and keep it from moving (though that probably has more to do with the size of the knife than the size of the clip). Its not a paint scraper either. Very good.
Man I agonized over this score. The lock works. Its strong and stable. It engages easily. But...eh...its hard to get at. The scales, as you can see:
Are cut up right around it, making it hard to wedge your finger in to disengage the lock. The lock works perfectly, its just not brain dead easy to disengage. If the scale were a little more refined, I would have given this something like a 1.5, but its not so I give it a 2 and note the shortcoming in the text. If you have thin fingers, this will be a non-issue. I don't have Polish sausage digits by any means and I still had a little trouble.
Overall Score: 18 out of 20
There are three places I am not perfectly satisfied with the knife, but none are huge deals. Each is a little niggling thing, like a mediocre side dish in an splendid seven course meal. As a package, the ZT0770CF competes with the best the production world has to offer in terms of high end, larger EDC knives. It is certainly in the same league as the PM2 and the 940-1. Its also the cheapest of those three, other than the S30V PM2 (is it time to stop calling S30V a premium steel? I think so...). I liked the 0770 a lot and I can see why Derrick liked it. If you don't have the coin for the 940-1 or you want a flipper, get the 0770. Its heritage may have been godlike, but this blade ain't no slouch. A demigod of larger EDC knives perhaps?
REVIEWZero Tolerance 0770: released a few weeks ago discontinued already?! Act fast!
A few weeks ago, it finallystarted showing up at dealers after a three year wait...then ZT removes it from their website and production ceases?!? If you want one, you may want to act fast!!!
One of the most anticipated knife families in history is Zero Tolerances 077x line its also one of the most popular knife families in history to see such an ill fate, and the similarities in naming, design, and ZTs poor communication on the topic of 077x production constantly confuses prospective buyers in terms of which product is which. Thus far, five different knives exist in the 077x family. This review pertains to the 0770, the least expensive (and smallest-sized) knife in the family. For those curious on this history of this product family, I have made a brief summary.
The ZT0770 is the spawn of the ZT0777 (prototype), ZT0777 (original model) and ZT0777M390. ZT introduced the original 0777 in 2010-2011. It used a full carbon fiber handle, in combination with titanium to form a modified Reeve Integral frame lock, with a composite blade that used Vanax steel and Damascus merged to form a single blade. It won the Blade of the Year at Blade in 2011. It took a few years before any made it to the market at all. When they did, a few hundred of the original models were made and ZT then stopped production. The blade was hard to make, gorgeous, and ridiculously expensive. The demand for this model has only grown since. With so few of these knives on the market, private sales have cleared $2,000.
ZT then introduced the 0777M390 (pictured below with my 0770). With the same handle/lock/blade style, the only difference was the blade was now one made with Bohler M390 super-steel. This run was also very short (perhaps 1,000 or so made with a stonewashed blade and another 1,000 with a black coated blade.) These knives quickly started selling for 2-3 times the MSRP of around $350. Final production figures on both this and the original are somewhat debated.
Around the time of the original 0777, ZT announced the 0770. The 0770 is a smaller aluminum-handled version of the 0777, with an ELMAX blade and a liner lock versus the frame lock. This knife was intended to be a production knife, but many sources have noted that production of this knife is already over and done with (and it only started being available about a month ago after 2.5+ years of waiting for it to see the mass market). So it presumably carries the ill fate of the 077x line and will likely increase in value if production has already ceased. It has since been removed from Kershaw/ZTs website, suggesting this in indeed the case and production is winding down or completed. The SRP was around $150.
ZT announced a third 0777 variant named the 0777CF shortly after they announced the 0770. This would be the same size and materials of the 0770, but use a handle made of a much more basic carbon fiber handle than the more expensive variants. MSRP is set for $225. It is unclear if this item will ever see mass market. Like other 077x knives, it has been on the radar for a few years but without much discussion from KAI as to what the status is.
---The 0770: My Take---
At first glance, the 0770 looks rather plain. The handle is black aluminum, the blade is a satin-stonewashed finish, there arent too many angles, and the markings are minimal. Its a very clean looking knife and visibly charming through its simple (and yet elegant) styling.
Intended as a smaller and cheaper version of the 0777, it incorporates a 3.25 inch ELMAX blade with a basic handle, liner lock, and deep-carry pocket clip. As you can see, this knife does not have thumbstuds. It only has the built-in flipper, but it is not a TRUE flipper. Unlike the 0777, the 0770 is an assisted opener that uses Kershaws SpeedSafe technology. Push the flipper so the blade opens about 35% and the SpeedSafe torsion bar will propel the blade to its full open-locked position. In order to avoid accidental engagement, the ball detent is MUCH stronger than on the 0777 and so it takes substantially greater force to move the blade from closed to the point in which it is propelled open. So there is a good chance users will love one style and dislike the other I personally prefer a manual flipper if there are no thumbstuds however, I also prefer flippers that have thumbstuds in addition to the flipper (such as the Rick Hinderer XM-18 or ZT0300).
The handle itself is well shaped, and handsome. It is simple yet ergonomic, and hands of all sizes can get a comfortable grip. I was hoping it would have excellent the spine jimping like the 0777, but unfortunately it has a much simpler pattern.
The blade shape is a really neat design. The cutting edge is technically on three different planes and it helps deliver even force when your hand moves in the fashion of a stroke by adjusting the cutting plane as you move your arm/wrist throughout the stroke. This gives some serious slicing power and its fantastic for cutting fibrous objects like rope, and for controlled cuts such as coring an apple. A knife this sized with this handle and blade shape/geometry/steel is at home in the kitchen performing the tasks one would use a paring knife for. It slices, dices, and chops well. Kershaw (ZTs parent company) is well-known for some unusual blade styles that attempt to increase cutting/slicing capability through geometric design the 077x series has followed this tradition (and improved it).
The blade steel is simply golden. It is made from a powdered steel, called ELMAX (by Bohler). ELMAX is capable of being hardened to 60-61 HRC, but with substantially greater toughness than older stainless steels many other stainless steels can become quite brittle at this hardness, risking excessive micro-chipping and premature edge deformation. ELMAX does not even at 60 HRC, its tough as nails and ZT does an excellent job at hardening this steel (along with the other 5+ powdered steels they use). As a steel with superbly balanced properties, it has excellent edge retention, fantastic toughness/impact resistance, fantastic corrosion resistance, and is very easy to sharpen and very easy to get to a point in which it can slice and bite. This last part is why I especially like the most recent generation powdered stainless steels
this video illustrates why
(link will start at 1:20 for the cutting to skip the demo)
Presumably, one of the reasons ELMAX gets so screaming sharp is the very uniform carbide distribution that steel freaks constantly are praising ELMAX/M390 for. There are very few steels on the market with the edge retention, toughness, and simultaneous ease of upkeep like ELMAX. If you are yet to own a knife with a blade made of one of the most recent powder steels like S35VN, ELMAX, M390, or CTS-XHP, you will be really happy with it. Think balanced properties of 154 stainless with similar ease of sharpening, but better in every category and with a huge increase in toughness.
The robustness of this knife is without question. The pivot joint uses ZTs most recent technology which is more or less an oversized pivot joint with heat-treated hardware designed specifically to hold up to frequent usage and to retain grease within the pivot system even when the knife is exposed to harsh conditions. The standoffs (backspacers) are oversized, secured with thick bolts, and there are three of them (many knives only have 1 or 2). For only 3.25 inches, the blade is pleasing (but not too) thick at .120 inches (and the grind tapers well so it can still slice despite being a beefy blade for a knife of this size) and of course with the blade steel being ELMAX, its going to give good performance with even heavy usage.
One thing that does not suffer here though, is weight & bulk. The use of aluminum has saved a ton of weight, and at only 3.75 ounces, it is less than half the weight of most other ZT folders. This smaller size/lighter weight/slimmer profile makes it more attractive for Every-Day Carry (EDC) for those whom are looking for a medium-sized knife. And a thin handle (with a thickness of under ½ an inch) also aids in making the knife a compact EDC.
The pocket clip continues ZTs trend of designing better pocket clips for their knives. It is a low-rider pocket clip and it sits DEEP in your pocket, doesnt wobble around, and is quite comfortable. However, it sits so deep that IMO it is much more enjoyable to use with a lanyard to help retrieve the knife from the pocket (as shown in the pictures). The 0770 can accommodate tip-up carry only, for both left and right hand carry (however, keep in mind the lock is right-handed).
---BUT, I didn't love it all...---
Unfortunately, I have two really big issues with this knife. The first is the liner lock. It is deep inside of the aluminum handles and it is hard to get good leverage on, especially with larger hands. Many people may not be able to close it with just one hand. The other issue is that the aluminum is quite slippery. These two issues magnify each other if you cant get good leverage to push the lockbar over to close the knife, and that knife happens to be slippery, it sets the stage for the knife to slip while attempting to close a live blade. This combined problem is further magnified by the knife being assisted opening you have to use physical force to close the blade against the torque the torsion bar is making that is used to open the knife and so if you slip, the blade is going to open up and move quickly.
Yeah I cut myself and the resulting trauma was quite deep and took a week of butterfly closures to keep the flap of skin closed. My hands are average size and I own hundreds of knives this is probably one of the five most difficult knives I own (or have handled in general) in terms of ease of one-handed closing. Smaller hands will work better and I imagine practice will overcome this still, I wish ZT would have textured the aluminum handle and/or flared the liner lockbar out more from the inside handles to make it easier to close. As much as I enjoy the rest of the knife, these two issues are enough reason that I will probably never carry this my general dislike of liner locks as locking mechanisms isnt helping either, as I find them to be far more prone to failing when dirty, harder to physically use, more prone to developing blade play, harder to tune and service, and not nearly as strong as the Reeve Integral Lock (AKA the Frame Lock) used on the Chris Reeve Sebenza, Kershaw Chive/Leek, ZT 0300, 0560, 0561, 0550, Benchmade Skirmish, Spyderco Ti-Sage, among others.
I figured I would write this up and throw it out there while models were still available for reasonable prices. Its a highly awaited knife, and other than my issues with the handle being slippery and lock to engage, its an awesome knife. If nothing else, its an awesome investment given the 077x line has made many a knife nuts some serious change (a buddy bought an original 0777 for $450 and sold it for $1,700 cash + a $500 knife!) ZT has a huge following and so anything that is limited or discontinued is a good investment given how many ZT enthusiasts there are. If you are looking for a knife in this class, you may like this knife but I would advise ensuring that you are able to disengage the liner lock easily, as you may find other knives in this class are much easier for true one-handed operation.
If this is a size/style knife that sparks your interest, you may also like the Spyderco Sage 2, Titanium (model SSC123TIP). While slightly smaller, the Ti Sage uses titanium handles with a Reeve Integral Lock I find the Ti Sage to be much easier to open, much, much, much easier to close, grippier from the textured titanium, far easier to self-service (most users will not be able to service the 0770), and a beefier build in general the prices of these two knives are similar. While I am a hardcore Chris Reeve Sebenza user, the Spyderco Ti Sage is one of my favorite knives made to date, and I think many people interested in the 0770 will fall more in love with the Ti Sage if they have a chance to handle the two together.
So its an awesome knife, but it does have some drawbacks, which other knives in this size/price/style/class do not. Financially, it's a pretty good bet to go up in value...and if you want one, now is the time to act before dealer stock depletes and the secondary market is the only place to get these!!!

Zero Tolerance Knives, the Made in USA hard-use offshoot of KAI Group, Inc, was displaying a very nice mid-sized folder in their SHOT Show 2013 booth. Rep. Andy Peterson showed me the prototype of the new model, which he said was a gentleman’s version of the Blade Magazine 2011 Knife of the Year, ZT’s 0777.
The new 0770 has a 3.25” stonewashed blade of Uddeholm Elmax® powdered steel. Elmax has high percentages of carbon, chromium, and vanadium, which result in high wear and corrosion resistance plus toughness. Rockwell harness of the Elmax is gauged at 58-62. I would call the blade profile a modified wharncliffe, having a slightly upswept cutting edge.
SpeedSafe® assisted blade opening is activated via a flipper. The liner lock is housed in dual 6061-T6 aluminum handles, which are anodized black. A reversible tip-up deep pocket clip and other hardware are blackened. The backspace is open and bridged by three bolsters at the screws.
The handle contour has a nice arch at the midpoint that fills the palm. Machined sides of the handle aid in grip. The inverted flipper provides a guard for the index finger. Jimping on the back of the blade is available to the thumb.
ZT states the knife is 4.32” closed and 7.57” opened. No weight is given, but my hand says it went about 3.3 ounces, give or take. MSRP will be $180.00, so look for it sliding into your pocket for less.
I thought the 0770 was a solid and pretty build from Zero Tolerance. I kind of wish ZT would name their knives, instead of just numbering, as I have some trouble keeping them straight in my head. Given 0770’s diminutive size but promise of sharp prowess, were I the marketing man, I would call it the “Gentleman’s Agreement.”

Zero Tolerance 0770CF Folding Knife; 3.25â High-Performance Crucible S35VN Steel Blade, Stonewashed Finish, Carbon Fiber Handle, SpeedSafe Assisted Opening, Liner Lock, Reversible Pocketclip; 3 OZ , black
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.
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.
Using a torsion bar to move the blade out of the handle, Kershawâs 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 bladeâs 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.
