Fällkniven CC4 Ceramic Whetstone Fällkniven present something everyone has been waiting for - a combination ceramic/ceramic whetstone that will handle your finest sharpening needs! The newly-developed CC4 whetstone consists of a super fine ceramic stone (white side) (2 micron) and a ceramic stone, made of synthetic sapphires (dark gray) (5 micron). You don't need any lubrication for these stones but now and then you should consider cleaning them with water and liquid soap. A leather pouch is included. If your knife is very dull we suggest you start by using a DC 4 or similar. If you knife is already fairly sharp but needs the edge polishing, start with the dark ceramic stone side and finish with the extremely fine white ceramic stone side. No not use water or oil. How to check the sharpness: To check the sharpness of your knife, pull the edge very lightly on your finger nail. If it cuts, the knife is certainly sharp enough for most tasks. Break in Period: Upon delivery, your new CC stone will appear slightly coarse. This coarseness will disappear when the stone is put to use and is totally normal, it is not a faulty with the product.
