   I have looked over this knife for a while and the reviews seemed mostly positive. So I decided to go ahead and order it. Packaging was adequate and the knife was bubble wrapped inside the box. Fit and finish were very good and the blade was seated about perfectly in the middle. The blade grind is fantastic and near perfect symmetrical. The knife is fairly lightweight and the pocket clip is adequate although it seems to be stainless steel. 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.

   Pocas navajas tipo flipper se encuentran con la calidad de esta ZT a este precio. Sin duda una excelente navaja, cómoda, funcional y polivalente, terminaciones de calidad. El titanio acabado “Stonewash” dota la empuñadura de buen agarre, es sólida, buen sistema de apertura y bloqueo. Sin duda una excelente compra.

   Es una navaja de bolsillo muy fina. Hecha en USA con escalas de titanio y acero de gran calidad. Muy elegante y la apertura a una mano es muy rápida gracias a que en el eje tiene baleros.

   Zero Tolerance Messer üben schon irgendwie eine gewisse Faszination aus. Wahrscheinlich liest du hier gerade in den Rezessionen, um ein besseres Gefühl bei der Anschaffung eines Taschenmessers zu diesem Preis zubekommen.
   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. 🙂

   Este artículo es una copia del original. Esta en dh gate por 55€. El original está fabricado en usa, no en China como lo indica la caja. El acero de la hoja de esta copia es distinto al del original. No recomendo para nada.
