The original Zero Tolerance 0454 was an award-winning collaboration between ZT and custom knife designer Dmitry Sinkevich. But it was also a very Limited Edition knife.

So ZT is doing something about that with the new 0450. While based on the original’s streamlined form and high-performance function, this new and more compact version will be much more readily available. With its 3.25-inch blade and lightweight-yet-stronger-than-steel titanium handles, the 0450 has a sleek and sophisticated look that, we think, makes it a perfect EDC.

ZT built it with an S35VN stainless blade that sharpens to a razor edge, holds it well, and can be resharpened easily. The knife opens smoothly and easily with the KVT ball-bearing opening system and built-in flipper. A titanium frame lock with hardened steel lockbar insert ensures solid lock up. Polished pivot hardware just adds to the 0450's refined good looks.

The original ZT 0454 was an award-winning knife, a collaboration between ZT and custom knife designer Dmitry Sinkevich. It was a Limited Edition knife, which means that it did not last long. To make up for this, ZT and designer Sinkevich came up with a near-perfect entry with the ZT 0450.

This is one good-looking knife. In fact, from every angle you are going to love this one. It is based on the original 0454's profile, but it’s more compact now and streamlined with an all silver or black & carbon fiber trim. Coming in at just 2.9 oz, this is a Zero Tolerance Knife that is versatile and easy to keep on your person throughout the day.

The ZT 0450 has a racy drop point, which makes it a great everyday carry knife. It has a predominant straight edge and a very sharp point. This cutter lives up to its capabilities and then some. If you have medium-duty tasks such as cutting through cardboard or plastic, you will love the 0450. You can even slice up food with it.

The stainless steel blade is S35VN takes a razor's edge and has great toughness and corrosion resistance. It holds up well and can be resharpened with ease. Opening the ZT 0450 is easy and seamless due to the KVT ball-bearing system in the pivot and the built-in flipper.

The titanium frame lock features a hardened steel lockbar, which ensures a solid lockup that will hold up over time. Polished pivot hardware makes the ZT 0450 a knife with smooth good looks.

The knife fits easily into any hand, with the index finger in the “groove,” the two middle fingers in the “valley,” and the pinky landing on the far side of the beak. When closed, this ZT 0450 allows for a slim and stylish profile that is very appealing.

Dmitry Sinkevich knows how to put a great-looking knife together. Visually, you are getting one of the most aesthetically designed knives out there. It is also made in the USA at the ZT factory where every knife is serialized and hand-assembled to maintain an exacting standard of quality.

The manufacturer does not allow this item to be sold internationally.

    Close to EDC Perfection

    Posted by Gearhead on 19th Nov 2015

    See my review on the ZT0452. All the stuff I said in that review applies here. Fits the hand very nicely. Beautiful grind on the blade. Fit and finish are excellent. Love the red standoffs! I usually choose a larger knife for EDC but I just find this one in my pocket a lot. Pocket clip is excellent. It doesn't need to be deep carry, especially ona knife this size. I like deep carry pocket clips but they can make it a little harder to get the knife out of the pocket. Flips like a rocket... as long as you keep your finger off of the lock bar. Actually, that's the one thing I have against this knife. I had to train my index finger to move back and rest on the pocket clip while flipping, otherwise this thing is hard to get open. I think ZT could change the detent pocket in the blade. It appears to be a straight sided hole that was dug out by an endmill. I won't remove a star though. It only took a minute to figure out how best to open it, but I definitely think it's worth mentioning.
