ZT Folding Knives
Zero Tolerance built its reputation on overbuilt folders, and the ZT folding knife lineup is where that philosophy lives. Every folder in the current catalog is Made in the USA, pairing premium steels with titanium frames, carbon-fiber scales, and canvas Micarta.
ZT Folder Design Collaborations
The backbone of the lineup comes from custom-maker collaborations. Rick Hinderer's XM-18 influence runs through the 0562 platform, where the thin slicer grind and titanium frame lock made it a benchmark tactical folder in the ZT catalog. Dmitry Sinkevich contributed the slimmer geometry behind the 0450, 0470, 0545, and Large Sinkevich, with thin titanium and carbon fiber handles that carry comfortably despite ZT's overbuilt reputation. Tim Galyean's work shapes the 0022 and Small Galyean, while in-house Kai design covers models like the 0044, 0707, 0117, and 0357.
Blade Steels and Handle Materials in ZT Folders
Steel selection spans CPM MagnaCut, CPM 20CV, S45VN, S35VN, CPM M4, and CPM Cru-Wear, depending on model and intended use. Handle construction follows the same tier-above approach: solid titanium frames dominate, carbon fiber shows up on the 0450CF, 0203CF, 0545, and Large Sinkevich, and canvas Micarta anchors the 0562MIC and 0004. Stonewashed, satin, bead-blasted, and black PVD finishes give the lineup visual range without compromising function.
Opening Systems and Lock Mechanisms
KVT ball-bearing flippers dominate the lineup and account for the smooth, effortless deployment ZT is known for. The 0044 DuraLock platform brought ZT into the manual button lock category in 2025 with ceramic ball-bearing washers and a titanium button cap. Frame locks remain the standard across most folders, typically with hardened steel lockbar inserts to prevent wear on the titanium scale. Sub-frame lock construction on select models cuts weight without sacrificing the secure lockup ZT demands.
Choosing a Zero Tolerance Folding Knife
If you're shopping the ZT folder lineup by use case, the 0450 family covers lightweight daily carry, the 0562 family handles tactical and hard-use cutting, and the 0357 and 0545 round out the accessible EDC tier. The 0044 is the pick for anyone who wants a manual button lock in a modern, slicing-focused package.
