Automatic knife. The Monaco is Pro-Tech's newest knife. Sleek, stylish and super fast. It delivers all the thrills of the Pro-Tech line. Black finished 154-CM blade (plain) and a blue jazz anodized T-6 6061 body with carbon fiber inserts (front and back). Although the Monaco's handle is slim and sleek, once open it's surprising how large the blade is and how much cutting real estate you actually have.
