Features of Zero Tolerance 0450 Folding Knife

Blade Details

This 3.25-inch blade has a beautiful drop point blade with a prominent top swedge. Drop point design has been majorly used in the ZT- Sinkevich collaboration majorly because of the functionality it offers.

Since everybody is going CPM S35VN for the blade material, you don’t expect ZT not to jump on the bandwagon; after all, they are renowned for high-end production knives. Crucible Powder Metallurgy (“CPM”) is receiving the entire buzz in the knife production circles because it’s one of the most balanced steel in the market today.

It boosts at scoring quite highly regarding stain resistance, ease of sharpening, ease of polishing as well as edge retention. Zero Tolerance 0450 treats S35VN steel to 59-60HRC to enhance its hardness. It also has a stonewash or satin finish which protects the blade from scratches.

Handle, Ergonomics, and Pocket Clip

0450 has the perfect balance between large and small enough to provide comfort. A good handle should provide a secure grip, and 0450 has excellent ergonomics thanks to its 4.1 inches which is a perfect size.

The handle is made from stonewashed aerospace-grade titanium alloy that is resistant to corrosion, and it’s also very lightweight but doesn’t compromise on durability. The stone wash is just perfect since it hides most of the daily wear as well as keeping the little flipper looking brand new.

The handle also has a reversible pocket clip as an additional feature to ensure that you have a deep carry that is easier to hold and conceal. This makes the knife to disappear in the pocket virtually.

Deployment and Lockup

First, the opening of this folder is nothing but magical. Seriously, is this the fastest opening mechanism yet! Alright, the point is zero tolerance 0450 sinkevich made complete use of their patented KVT ball-bearing system because it’s pure perfection.

The KVT ball-bearing pivot has a reliable, fast one-hand deployment. The detent has softened, and it’s as smooth as it can ever get. Clearly, this is the most fun feature of the knife that you just can’t stop gushing about it.
The lockup feature is also worth writing home.

ZT has put steel inserts between titanium lock bars and the hardened blade of the steel. The steel lock bar insert doubles up as an over-travel stop that prevents you from pushing the lock bar far enough to ruin the lockup. With such a sturdy frame lock bar, you have one less problem to worry about.
