For Zero Tolerance performance, the blade is S35VN powdered steel, which provides the ability to take a razor edge, excellent edge retention, strength, and toughness. A Blackwash finish on the blade hides hard-use scratches and makes maintenance easier. The sweeping lines of the original 0777CF are preserved in the lightweight aluminum handle that fits securely in the hand. An inset liner lock secures the blade. The 0770 opens quickly and easily thanks to SpeedSafe assisted opening and the built-in flipper. Includes deep-carry pocketclip. This is a great knife for anyone one looking for a tough and reliable everyday carry knife.
