Fallkniven CC4 Ceramic Whetstone

The CC4 whetstone is designed for honing and finishing folders, fixed blades, kitchen knives, and more. It has two sides: one side made of synthetic sapphires (the dark gray side) for initial sharpening and one super-fine ceramic stone (the white side) to finish off the edge. To use it, just rub your blade on the surface at an angle in a circular motion, gradually removing material from the edge. Then flip it over and complete the process. Neither side requires lubrication, either—just wash it with soap every once in awhile, depending on how often you sharpen your knives.
