The Zero Tolerance Hinderer 0550 features a bullet-tough blade of Crucible's S35VN stainless steel with stonewashed finish. The steel is designed to offer increased toughness over S30V, yet be easier to machine and polish. It offers high wear resistance and resists edge chipping. It's chemistry includes niobium, vanadium and chromium carbides and offers an exceptionally uniform distribution of those carbides, too. In other words, this high-performance knife can take whatever you can dish out. Designed by Rick Hinderer.

Great ZT knife!
I've owned and carried a 0550 for a couple of years and have no complaints at all. In fact, I like the knife enough to purchase the newer model with upgraded lock-up. I've never experienced lock failure on the old model as some have though. When I saw the lock-up had been redesigned with a hardened and removable insert being added I decided to purchase the new model. The new model is just like the old, very solid with a heavy blade and great steel that holds an edge. The only complaint someone might have with this knife, especially for EDC, is the weight. At just over six ounces it is a little on the heavy side but overall excellent knife!

70-75% knife for the price
To be honest I expected nothing less than perfection and I am a little disappointed. Ill start with the PROs (imo): -quality materials, great precision in the grind lines and in the Ti milling on the frame; -elaborate design, ergonomic in hand; -centering is PERFECT; -good traction on the G10 scale (and I even like the not-so-popular pattern); -nice stonewash on the blade; -overall great looks (that's why we buy these things in the first place, am I right?). Now the CONs: -first HUGE con is that the metal insert on the frame lock makes it very sticky. Its annoying for such an expensive knife; I really wanted to believe they got the locking mechanism perfect, especially on a 3rd gen (I thing the first gen was better?); -this knife takes A LOT of breaking-in time; I only now (after weeks of use and playing with) am able to open it one-handed, especially with my right hand. The ball detent was so strong in the beginning that it was impossible to open and it dug a hole in my thumb (blood and everything, no kidding) when I tried. On the left hand it was easier, and still is, because you don't go against the lock bar. Works fine now, after my thumb healed; there is also a technique to be learned. Not an easy knife to use, and again, disappointing for its price; -good luck trying to use the pocket clip on the left side! The G10 scale is just to slippery under the clip for it to stay in place. If they actually wanted to make the knife ambidextrous, why don't they just mill a groove under the pocket clip (and I know they can, since there is already a lot of good quality milling on this knife). Its funny to me that they can make such quality products but are not yet (3rd gen!) able to make the darn pocket clip work. I guess im lucky to be right handed; -the edge was medium-high sharp (Cold Steel can give you a scary sharp edge for 40 bucks); -one of the standoffs that hold the handle together does not fit perfectly on mine; -I whish the pocket clip was stonewashed to match the blade, and I whish the frame on the G10 side was made of titanium, it would be more fair, for the price. This is not really a con (as you should do your research before buying this knife) but just a word of advice: this is not an EDC friendly knife. It is chunky and noticeable in the pocket, although they've made efforts to make it lite. As I said, I am a bit disappointed overall, mostly because of the sticky lockup. I'm sure I could contact KAI and they would fix it for me (this is the easiest company to deal with that I've encountered to date) but I live in Europe and I don't really want to send the knife back and fourth too many times.

Amazing right out of the box
I just got mine today so I can't yet speak to long term use, but after reading a number of other reviews I wanted to address a few key complaints I've heard from others. First off, the G10 side is exactly as grabby as every other G10 handle I've felt (if anything, a little less). I think it's perfect. Second, mine opens very smoothly and with little to no effort. I noticed there's a small ball bearing (or something like that) mounted on the lock bar which rides against the blade. I'm wondering if some simply require more break in than others? At any rate, mine opens great right out of the box. The knife is amazingly well made. After close examination I can't find a single flaw. It fits in my pocket perfectly and came razor sharp. I'm VERY happy with my purchase. Some folks may find this knife a little too heavy, but I honestly don't think those people are going to be looking at a knife like this in the first place. To me it's just right.
