From the manufacturer
A cut above the rest
From fierce combat knives to lightweight EDCs, Zero Tolerance consistently dedicates the iconic brand to offering premium-quality, professional, hard-use knives consumers can depend on. Zero Tolerance knives are manufactured with premium blade steels, high quality handle materials, and dependable locking and opening systems.
Zero Tolerance Sinkevich Knives
Custom knife and toolmaker, Dmitry Sinkevich, has collaborated with Kershaw and Zero Tolerance to achieve some of the most elegant, everyday carry folding pocket knives designed with clean lines, sleek looks and solid ergonomics. With practical design and enhanced detailing, Sinkevich’s characteristic clean and practical design is adorned by knife lovers everywhere.
Attractive Blade Finish
When a knife design requires a lighter blade to highlight the steel, Kershaw often applies a satin finish. Satin finishes, whether machine-generated or otherwise, leave faint patterns of lines on the steel, and while they sand away the steel’s brightness, they do not remove it as completely as do other finishes. A satin finish also helps reduce evidence of stains and scratches on the blade. Depending on the knife’s design, Kershaw’s non-reflective stonewashed finish may be either pronounced or subtle, but in both cases, it transforms the blade by creating a fade-resistant, scuffed look that hides smudges and fingerprints. A stonewashed finish, achieved by tumbling a blade with ceramic stones, enhances a blade’s rugged appearance as well as its indestructibility during field use.
Using 'caged' ball bearings for smooth blade deployment and overcoming stronger knife detent, the KVT Ball-Bearing Opening System makes one-handed knife opening fast and easy without the need of a mechanical assist. Ball-bearings surround and freely rotate around the pivot. When the user pulls back on the flipper, the blade rotates out of the handle as the ball bearings roll into place.
Secure Locking System
Kershaw’s frame lock design makes knives safer, securer, sturdier and quicker for one-handed blade deployment. The knife handle, or frame, has two metal plates on either side of the blade, and when open, the lockbar butts up against the blade’s backend to prevent blade closure. To close the knife blade, push the frame to the side to unlock the blade and fold the blade back into the handle.
Flippers on manual-open knives require user to push with quick strength until blade deploys. Some manual flippers disappear when blade deploys, others become a finger guard. Manual flippers appeal to inexperienced users as well as experienced users who prefer a classic, old-style opening. In both cases, ambidextrous flipper works as index finger applies pressure while closed knife sits in palm.
Titanium is a lightweight metal alloy and it offers excellent corrosion resistance. Heavier than aluminum but still lightweight and strong, titanium is a very sturdy material often used in knife handles, locking liners, or as a blade coating to enhance performance. Titanium is a sleek, stylish, premium material that’s excellent for the ideal everyday carry.
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. A pocketclip with tip-up carry is positioned so the closed knife carries in the pocket with the tip of its blade pointed upwards. A reversible tip-up or tip-down pocketclip allows user to change tip position.

From Zero-Tolerance’s popular 0450 original, comes the 0450CF, now with a carbon fiber handle, a dark, refined appearance and even more staggering style. The 3.25-inch high-performance blade is made from S35VN stainless steel for amazing toughness and corrosion resistance, and a sharper, longer-lasting edge. The blade’s DLC (Diamond-Like-Carbon) coating lowers friction and enhances performance through increased hardness and wear resistance, while simultaneously adding intensely sleek good looks. The 0450CF’s handle features a carbon-fiber front scale for a solid, balanced knife construction and lightweight convenience. Manually open with ZT’s KVT ball-bearing system, deploying the blade smoothly and quickly, and confidently operate while the DLC-coated titanium back handle scale’s frame lock secures the blade open during use. Zero Tolerance crowns the durable 0450CF with a reversible pocketclip and two emerald-green anodized aluminum tube spacers for a discreet touch of personality.

The deployment is very fast and smooth. As others have mentioned, getting the blade past the bearing detent for deployment is a little stiff. It does cause a little bit of discomfort the first few times your deploy the blade but if you just do one firm press then it hasn't been an issue for me. I actually do like that it is tighter closed so it won't accidentally open in my pocket or if someone else is handling it. I think it would have been nice to have a thumbstud as an option to deploy the blade but the look is overall cleaner without it and it is one less thing to catch on your clothes or pocket.
Another issue I had read about before buying seemed to only come from one reviewer and it regarding the liner lock. The issue I read was that once deployed, if held firmly that the liner lock would squeeze all the way to the opposite handle causing the lock to just about fail. I have not experienced this and feel like that reviewer might have got a defective knife. The blade locks up nice and tight and coming from older titanium frame lock knives, I really appreciate the steel plate in the frame lock so that the hardened steel of the blade doesn't have to lock on the softer titanium in the frame. This would lead to faster wear on the titanium which could compromise the lock at some point. Also the steel plate is removable which mean it is potentially replaceable which would make lockup nice and tight again if needed.
The Spyderco Sage 2 is a great knife and has possibly the best ergonomics I've ever felt on a knife. It fit the hand and felt like just an extension of the hand. The 0450 isn't quite that same feel but it is excellent for my medium sized hands. The flipper comes around and acts as a perfect finger guard along with the shape of the handle. I have little worry of my hand being somehow able to slip past the guard and cut myself, It seems improbable if not impossible. The jimping on the back of the blade is fairly aggressive. It is sharp enough to add real grip but not enough to catch your pants or cut your finger. I would have loved to have a crowned spine on the blade to make this more of gentlemens knife but having the flat spine leaves less chance of your finger slipping.
What I really like about this knife as an edc blade is the slender and slim profile of the knife that makes it very easy to pocket. It just doesn't take up that much room in your pocket and yet offers a long and very functional blade. The pocket clip is a bit plain and tacked on. I immediately ordered a titanium deep pocket carry clip to replace it and wish it came with one to begin with. Still the pocket clip works and doesn't kill your pockets too much.
The blade is a little aggressive in design and I only mean that as in people might be slightly scared seeing it. It has an unsharpened swedge and has a very long and sharp point which makes it look more "tactical." However it has a good sweeping and functional belly for such a thin knife. This is my first knife using S35VN but have used everything from 440c to 154CM to VG-10 to D2 to S30V. S30V is one of the best blade steels I have used in terms of corrosion resistance, edge retention, and ease of sharpening. It is just a fantastic steel for pocket knives and I don't think many people would dispute that. S35VN is nearly the same but supposed to be tougher and easier to grind and work on with the addition of the niobium to the formula. So far I have no reason to doubt that is the case. Either way these steels were made for knives and it shows.
If I had to make one complaint it would just be a minor design issue. On the frame lock side of the knife the two screws that hold the red standoffs just terminate into nothing. You simply see the flat bottom of the screws on the handle opposed to knives that use screws on both sides of the handles. This is only aesthetics and has likely no effect on function but considering how elegant and stylish this knife is, it would have looked even nicer with screw heads on both sides. It is such a minor non-issue but something I noticed.
I have owned and handled many knives and I have to say this is close to my idea of what a perfect pocket knife would be. What I want from my pocket knife is solid quality construction, titanium handles, RIL or a liner lock of some kind, high quality but easy to maintain blade steel, functional blade grind and shape, good ergonomics, and small and light profile for edc. The Zero Tolerance 0450 meets all those requirements for me and even adds a few new ones. The price is absolutely reasonable for the quality construction, design, and materials on the knife and that makes this very easy to recommend.
After reading a handful of reviews for ZT knives, I see that there seems to be a trend: "I bought other knives (Spyderco, Benchmade, Boker, you insert your fav brand) for years and carried them as my EDC. But I had a revelation when I got my first ZT. Smooth. Quality. Couldn't put it down, cuz it is so much fun to flip..."
I find it very refreshing that ZT can produce a product at such a high quality level that it makes buyers giddy with joy. Awesome! Goodonya ZT!
This might be my first ZT, but I look forward to purchasing many more ZTs. If you do not own a ZT yet, pony up, you will not be disappointed. Then you too, can join the ranks of giddy ZT owners! Zero Tolerance Knives: Highly recommended!
This beauty is easily my new favorite and well worth the price. It's silhouette both open and closed are gorgeous, with long, elegant, and clean lines. The blade is made of a fantastic steel with a perfect satin finish and tasteful sledge and is wicked sharp out of the box. The bead blading on the handle is also masterfully done. My favorite touches are the polished pivot and Ruby red standoffs. It's just enough bling while keeping it's classy character.
The blade action and detent are also suberb; easily up the with the CT sebenza. I credit this to design, the KVT ball bearing system, ceramic washers, and weight to length ration. Some have complained about the knife being difficult to deploy, but honestly that really only comes down to knowing how to open a frame lock knife. The only knock I have (a minor) one is the pocket clip, and that's only because I generally prefer a deep carry clip. I have custom satin finish deep carry clip on the way. Pay for quality, put out the dough, and enjoy this masterpiece everytime you look at, deploy it or use it!
Update: I just discovered this knife strikes a fire-steel like crazy! It isn't a bushcrafting knife, but it is nice to know I can use it with the little firesteel that I keep in the truck if need be. Upgraded to 5 stars.

Klar, super Stahl und die flipper action ist ebenfalls genial. Aber, wenn wir ehrlich sind, dann sind die Dinger überteuert. Made in USA hin oder her...
Kommen wir zurück zu der Faszination. Die wird bleiben. Du kannst dich jetzt mit einem China Messer vorerst zufrieden geben, aber wir wissen beide, dass du schon bald wieder hier auf die Fotos starren wirst.
Also, spar die günstigeren Ersatzmesser! Wenn du ein ZT haben möchtest, kommst du über kurz oder lang eh nicht drumherum. :-)
Flipper très efficace et ouverture très fluide.
Frame lock très efficace.
De taille très discrète pour un edc il est cependant un peu trop petit pour la grandeur de ma main (mais je m'en doutais!).
und funktionalität sehr gut!
Nur mir persönlich zu klein.
Plaquettes titane légèrement rayées
Fil du couteau marqué (légèrement)
Donc couteau d’occasion !!!
