EDC Knife Review: Zero Tolerance 0450 Sinkevich KVT

Kai USA Ltd., owner of Zero Tolerance and Kershaw knife companies, seeks to ensure there is a knife for everyone. Its line of Zero Tolerance (ZT) knives typically represents the higher end, with a reputation of being proudly “overbuilt.”

The 0450 from ZT is a slightly more compact version of the original Limited Edition 0454, which was developed in cooperation with custom knifemaker Dmitry Sinkevich — also the designer of the 0462 Sinkevich folder. I was thoroughly impressed with the 0462, and I figured that I would be equally impressed by the 0450. I was right.

While the 0462 is a larger, ultralight folder with carbon-fiber handles, the 0450 makes use of lightweight — although heavier than carbon fiber — titanium throughout its construction. Titanium, a silver-colored, low-density metal discovered in 1791, is stronger than steel and resistant to saltwater corrosion.

Zero Tolerance 0450 Sinkevich KVT Titanium Tactical Folder Specifications

The USA-made 0450 has a closed length of 4.1 inches. Its 3.25-inch blade gives the 0450 an overall length of 7.4 inches, which keeps you from running afoul with jurisdictions that don’t like knives with a 4-inch or longer blade. Its size positions the 0450 right between a utility folder and a combat folder. This means that the 0450 is small enough to ride comfortably in the pocket as an everyday carry knife, able to handle daily chores while still providing a modicum of defensive capability.

Closed Length Open Length Weight Handle Material Blade Material
4.1 inches 7.4 inches 2.9 ounces Titanium CPM S35VN Steel

I can’t stress comfort enough when you are thinking about something you might be carrying every day. Your handgun, reloads, light and anything else you plan on packing can add up rather quickly. So anywhere you can save overall weight and reduce overall size is critical in determining what kind of mood you go home in. The 0450 keeps you lightweight and happy.

The 0450 weighs 2.9 ounces. By way of comparison, the larger ZT 0909, more of a true combat folder, weighs in at 7.5 ounces. When carried in the pocket for eight hours, the difference is pretty noticeable.

The ZT 0450 Sinkevich KVT Is One Good-Looking Utility Knife

The blade is CPM S35VN steel, which is a hardened, corrosion-resistant vanadium stainless steel specifically developed for knifemaking. And it is razor sharp! It sports a combination stonewashed and satin finish, which gives a very eye-catching look. The titanium handles are also stonewashed. There is a lanyard hole at the end of the grips for extra security, if you wish, and the pocket clip is reversible.

The 0450 utilizes ZT’s KVT ball bearing opening system, which is very quick despite not using a spring to assist. It is activated by a finger flipper — the opening method I prefer. The frame lock is titanium, with a hardened-steel lockbar insert for solid lockup. For an added touch, the pivot lockwear is highly polished to a bright chrome-like finish. Two of the grip bolsters are colored bright red to create a signature visual appeal as well.

Once open, the 0450 balances well in the hand, and the finger flipper acts as a guard for the index finger. The top of the blade has a series of six grooves to keep the thumb from slipping. Good thing because ZT knives are very sharp! The 0450 slices open shipping packages with aplomb.

The ZT 0450 Sinkevich KVT Titanium folder is a very well-designed tool. Moreover, the ZT name imparts a strong dose of ownership pride. MSRP is $235.
