The CRKT Sero in black is a 3.02-inch folding knife from Columbia River (brand part no. 7170K) that blends refined Art Deco styling with modern performance in a knife that feels as natural in the pocket as it does in the hand. The low-profile flipper smoothly deploys the TiNi-coated S35VN blade thanks to an IKBS ball-bearing pivot, while the black textured glass-reinforced nylon handle keeps the Sero lightweight and durable. An intuitive Crossbar Lock offers solid lockup, and its tip-up ambidextrous carry makes it comfortable for both right- and left-hand use. A pocket clip is included for secure carry.
