The Cold Steel 3-in-1 Knife Sharpener is equipped with two sharpening stones set at fixed angles. One stone is made of ceramic while the other is crafted from carbide. The carbide stone is designed to quickly restore a sharp edge while the ceramic stone refines the blade to a finer razor-sharp finish. Additionally the sharpener includes a fold-out rod coated with diamond dust perfect for honing serrated edges or small gut hooks. Key features include a coarse carbide slot for swift sharpening a ceramic slot for achieving a fine edge and a tapered diamond-coated rod suitable for both serrated and straight edges. Its compact design also includes a lanyard loop for easy portability.
