ZT 0450
The Zero Tolerance 0450 is Dmitry Sinkevich's benchmark EDC flipper and one of the most carried knives in the ZT catalog. Sinkevich developed the platform as a compact evolution of the award-winning 0454, shrinking the footprint to a 3.25-inch drop point while preserving the clean lines and balance that made the original a Blade Show winner. The 0450 is the knife that proved ZT could build a gentleman's daily carry without abandoning the overbuilt standards the brand was founded on.
The 0450 Platform
Every 0450 variant rides on a titanium frame lock with a hardened steel lockbar insert, KVT ball-bearing pivot, and a reversible deep-carry clip. Closed length runs 4.1 inches with an overall length of 7.4 inches. Weight starts at 2.9 ounces on the full-titanium version and drops to 2.4 ounces with carbon fiber front scales. Blade geometry is a slim hollow-ground drop point with a pronounced upswept tip for detail cutting and a belly that handles general EDC slicing without drama. The flipper tab carries shallow jimping for deployment purchase without tearing up the finger on daily use.
Blade Steels Across the 0450 Lineup
The standard 0450 runs CPM S35VN in a satin-stonewash two-tone, offering the balance of toughness, edge retention, and sharpenability that made it a staple premium steel. The 0450CF keeps S35VN in a DLC-coated black finish paired with carbon fiber front and titanium back scales. For buyers chasing the upgrade path, the 0450BLUCF adds CPM MagnaCut, the corrosion-resistant powdered stainless from Crucible that has become the current benchmark for EDC steel. The 0450CFDAMS Small Sinkevich is the collector's variant, pairing orange and red carbon fiber scales with a ladder-pattern Damascus blade for buyers who want a showpiece built to the same working spec as the production run.
Who the 0450 Is For
The 0450 is the pick for anyone who wants a flipper that disappears in the pocket without sacrificing premium materials or authentic custom design DNA. Tech workers, professionals, and hobbyist carriers all gravitate to the 0450 because it reads clean in an office setting while still cutting above its weight class. It's the entry point to the Sinkevich ZT lineup and usually the first ZT most carriers add to their rotation.
