As I have said before, I have many pocket knives stashed throughout my hectic world…in my cars, desks, tool bag, EDC gear, etc. They are a very useful tool to have around when needed. Most of my knives range in quality from good to very nice and the Zero Tolerance 0460 by designer Dmitry Sinkevich is no exception. I received this titanium and carbon fiber “flipper” from for this review and it hopefully only raises the collective average of my collection…let’s see how it fairs.

A bit of background:

ZT Knives – Premium American-made tactical folding knives

Zero Tolerance Knives (or “ZT Knives,” as their dedicated fans sometimes say) provide the cutting- edge performance their name suggests. All Zero Tolerance models are American-made with the goal of extremely high manufacturing tolerances and top-shelf materials, a merger of function and performance.

The ZT 0460 has a manual flip blade made from stainless S35-VN steel. The blade has a satin stonewashed finish and a Rockwell 60-62 hardness. The lines of the ZT0460 flow very well giving it a great look, balance, and overall feel in the hand. The blade is 3.25 inches long and 0.12 inches thick. It is made from high-quality American-made steel, CPM S35VN with niobium, vanadium, and chromium carbides. This alloy has increased toughness and wear resistance against chipping that theoretically stays sharp longer.

The flipper blade pivot has a KVT ball-bearing system making the knife easy and intuitive to open.

  • MAKER: Zero Tolerance Knives Design by Dmitry Sinkevich
  • BLADE SIZE: 3.25″ Long
  • TOTAL SIZE: 7.5″
  • BLADE MATERIAL: Stainless S35-VN Steel – Satin Stone Washed – Rockwell Hardness 60-62
  • HANDLE: Carbon Fiber
  • FRAME: 3D Machined Titanium – Frame Lock has a Hardened Steel Lockbar Insert
  • WEIGHT: 2.3 oz.

The handle of the ZT 460 is 4.25 inches long. The frame and frame lock portion of the handle is machined from stone washed titanium.

The opposite side of the handle is made from a bronze carbon fiber composite that is not only lightweight but distinctive as well.

The handle has a hardened steel lock bar insert and a raised, textured spacer for a positive grip. The titanium side of the ZT 0460 has a removable, Zero Tolerance monogrammed belt/pocket clip.

The combination of carbon fiber and aerospace-grade titanium makes the handle durable yet lightweight. Add in the stainless steel blade and the total weight of the ZT 0460 is 2.3 oz.

The ZT 0460 flipper has a reliable, well-engineered frame lock design. When the blade is extended, the frame bends inward to lock it securely in place with zero blade movement.

To close the blade, simply press the frame lock aside and the blade smoothly rotates back into the closed position. The ZT 0460 does not have a closed locking mechanism that keeps the blade from accidentally opening.

As I said above, the Zero Tolerance 0460 is a great size and weight with a solid, well-balanced feel…making for an excellent EDC choice.

The 0460’s stainless S35-VN steel blade is extremely sharp as you would expect but the curve creates a serious point on the business end of this flipper.

That said, the Zero Tolerance 0460 by Dmitry Sinkevich when closed is very unassuming and non-threatening. I have been using this knife for a few weeks and it would make for an ideal addition to anyone’s EDC gear. Its design, size, weight, and quality make for an excellent travel companion or with-you-all-the-time tool. The ZT 0460 flipper is very well made with high-quality materials and will definitely make a great member of my pocket knife collection without a doubt.
