Our Verdict

The Zero Tolerance 0450CF resides in the exclusive and stratospheric world of high-end, readily available pocket knives. If you want to quickly and easily place an order for the best possible pocket knife, your options are limited to this and just a few others. You can dig deeper, shop longer, and engage in a dialog with knife boutiques, and do slightly better. But you can't do much better than this on the mass market. The ZT is well made of excellent materials. Our only "complaints" are in design matters. We wish the handle were a little bulkier for heavy tasks and we wish it had assisted opening with thumb-stud activation. Our high-end award winners incorporate these important design cues and the result is that we can't grant an award to the ZT. If you like its design more than we do, you'll not do better.

Our Analysis and Test Results

The absolute best (and most expensive) pocket knives are made by small, boutique outfits and are available in extremely small production runs. We don't review them here, as our findings might be different with the next production run or you might not be able to purchase a new knife like that anywhere, anyhow. Where the market for widely-available, readily-compared pocket knives tops out is where the Zero Tolerance 0450CF sits. When you eliminate pocket knives that are not readily available at retail, this ZT and just a couple of others (that often win awards with us, incidentally) top the market. The 0450CF is made with premium materials, close attention to detail, and sells for a price that reflects all this. We like the 0450CF a lot. At this price point, though, we like others a little more. This ZT doesn't win any of our awards, but that doesn't mean that it isn't just as good as virtually any pocket knife we've ever tested.

Blade and Edge Integrity


S35VN stainless steel is the best steel we know of for mass-produced, widely-available knives. Zero Tolerance shapes it into a nearly-perfect configuration. We can't think of how we'd improve this blade. Our cutting experience has been flawless. It holds an edge better than most. The blade and edge geometry that ZT uses is carefully tuned and balanced for precise cutting and longevity. Every millimeter of the edge is usable. No thumb stud, hinge hardware, or blade "tang" protrusions interfere with the use of the edge. This is an easily overlooked blade attribute that really affects your use of it.

We love the blade of the Zero Tolerance 0450.

Ergonomics


The Zero Tolerance 0450 is a full-length pocket knife with a relatively narrow (in both dimensions) handle. Its pocket clip can be configured for either right or left pocket carry (tip up only). It locks open with a frame lock. The 0450 opens with two hands or one. To open it with one, ZT designed it with a "finger flip" style deployment.

We wish the handle of the 0450CF were a little bulkier for the heaviest and most extended of tasks.

The handle isn't as bulky as we'd like for optimum ergonomics. The carry options are nice. The frame lock works every time. Finger flip opening isn't for everyone. If you like it, you like it. However, most of our test team prefers thumb-stud opening. Some knives open with finger flip or thumb stud. ZT committed to the finger flip mode.

The blade took on some strange, moving colorations. Best we can tell it has something to do with the way the coating interacts with oils. It didn't affect the ground, sharpened portion of the blade.

Portability


The 0450CF knife is about average in bulk and mass. The pocket clip is fairly standard; some of the knife's handle will show above the edge of your pocket. The semi-sharp exterior angles of the knife and handle will exert some wear on the inside and edge of your pants pockets, but not a lot.

Construction Quality


You expect a knife at this price point to have the best materials and for those materials to be assembled immaculately. You get that, for sure, with the ZT 0450CF. The carbon fiber scale, for instance, saves just grams and adds significant cost. This is a no-compromise tool. The frame lock has a reinforced, presumably replaceable working surface. The pocket clip is so tight that it pulled threads from the fabric of our pants pocket, which brings us peace of mind that this expensive tool won't slide out unintentionally. This is a well-made product.

Other Features


There are no other features on the 0450CF to report on.

Value


You don't choose a knife like this for its value. You choose a knife like this for optimum performance, durability, craft, and "flash." The carbon fiber alone is a showy choice. It lends little to no performance advantage but lends great appeal nonetheless.

You know it is a high-end product when it has a serial number. The Zero Tolerance knife offers incredible steel to boost its blade integrity.

Conclusion


It is easy to find mid-priced knives to review. It is actually somewhat hard to find readily available top-of-the-line pocket knives. Generally, it seems, connoisseurs of high-end pocket knives like to source them from boutique, one-off manufacturers. Shopping and selection and customization are part of the consumer experience for many of these users. Those consumers have little need for our reviews. If you want the best, but don't want to make a job of working with the manufacturer, your options are more limited. In those limited options, the Zero Tolerance 0450CF is a top contender.
