The Zt- Zero Tolerance 0220 Jens Anso Flipper Knife Titanium Stonewash Plain Edge. The Zero Tolerance 0220 represents the first collaboration between ZT and Danish knife-maker Jens Anso. This flipper knife offers a sleek and practical design with custom touches that add a collectible appearance. The modified drop point blade is made from S35VN steel with a durable stonewashed finish. It has a titanium handle with a deep carry pocket clip that is reversible for left or right hand carry. It comes in a bead blast finish which makes a nice contrast with the stonewashed blade. Zero Tolerance's KVT ball bearing system makes opening the knife fast and easy. Decorative elements of the 0220 include a ZT logo medallion on the handle and an anodized aluminum backspacer that serves as a lanyard hole.
