The Gerber Controller Fillet Knife System was created with the angler's needs in mind. These knives have killer 9Cr corrosion-free steel designed to hold an edge. The fixed blade handle is encased in glass-reinforced nylon, giving it an edge in strength. Under wet and slippery conditions, the HydroTread Grip featured on the handle ensures optimal safety for the angler. Control fins for your thumb deliver unrivaled control while the handle, specifically designed for your palm swell, will lock your hand in place for great leverage.
