The Edge Master Diamond Retractable Sharpener allows you to sharpen your knives like a professional. This handy tool is just the size of a pen so you can have this clipped onto a pocket, for easy access. Just loosen the screw cap and pull the diamond rod out to the desired length and then tighten the screw cap so that the rod will not move. Perfect for sharpening for both flat or serrated edges and also includes a groove to sharpen fish hooks.
