Zero Tolerance 0230 Anso Double Detent (0230)

Minimalist design meets maximum performance in the new 0230 from ZT and Danish designer Jens Anso. But the 0230 is ZT’s first slipjoint knife, so we had to add some extra touches to this non-locking pocketknife.

The 0230 features a double-detent system: two steel detent balls, one on each side of the blade. These hold the blade safely closed for carrying. Then, for controlled open and close, the 0230 also has a half-open position.

The blade is CPM 20CV for exceptional wear resistance and a long-lasting edge. The highest level of chromium of any high-vanadium steel gives it excellent corrosion resistance as well. The sheepsfoot blade shape, with a full-width flat grind, provides excellent slicing capabilities and the downturned tip is ideal for utility work and precise, controlled cuts. You’ll also notice that there’s no logo on the side of the blade. To maintain the knife’s clean look, we put our name on the spine instead.

The handle is carbon fiber, making this an exceptionally light and easy carry. The backspacer is anodized in blue and features an integrated lanyard attachment. The knife’s unique features and the clean Anso design make the 0230 a simple, yet extraordinary knife.
