The Zero Tolerance 0770 is a Limited Edition model that features an aluminum handle and assisted opening. It is a stream-lined version of the award winning ZT 0777 so you get the style and performance of of the 0777 in a slightly smaller version. The blade steel is S35VN which provides a razor edge, excellent edge retention, strength, and toughness... everything you want in a quality folder blade. A black DLC finish on the blade hides hard-use scratches and makes maintenance easier while providing a distinct tactical look. The flowing lines of the original 0777 are preserved in the machined aluminum handle that settles securely in the hand. The aircraft aluminum handle is anodized for strength and to enable the material to accept a scratch-resistant OD Green coloring.The 0770 opens quickly and easily thanks to SpeedSafe® assisted opening and the built-in flipper. Includes deep-carry pocket-clip that can be positioned for right or left hand use. For a final touch of class, ZT adds a handsome over-sized pivot.
