Liigendnuga CRKT Sero, aqua

The Sero is everyday carry, redefined.

Designed by knifemaker Richard Rogers, the Sero blends refined Art Deco styling with modern performance in a knife that feels as natural in your pocket as it does in your hand. The low-profile flipper smoothly deploys the satin-finished S35VN blade thanks to IKBS™ ball bearing pivot, while the light green glass-reinforced nylon handle keeps the Sero lightweight and durable.

An intuitive Crossbar Lock offers solid lock-up and its tip-up ambidextrous carry makes it comfortable for both right and left-hand use. Every line of the knife reflects intentional design—the flipper tab flows seamlessly into the bolster, creating a cohesive profile whether the knife is open or closed. With the Sero, Richard Rogers brings the precision and artistry of custom knives to a practical, pocket-ready tool.
