Fällkniven CC4 ceramic pocket sharpening stone

The Fällkniven CC4 is a double-sided ceramic stone made of synthetic sapphire. The stone can be used dry and should occasionally be cleaned with warm water and a mild liquid soap. The stone can feel a little rough to the touch, but becomes smoother during use. The grain size of the dark size is 1 micron. With it you can sharpen your edge with razor-sharp results. The white side, with 0.1 micron, is even finer. This side is mostly suited when polishing sharp knives. For sharpening dull blades it is wise to start with a coarser stone.
