The DC-4 from Fallkniven Knives is a combination diamond/ceramic whetstone that will handle all your sharpening needs. The newly-developed DC4 and DC3 whetstones consist of a fine diamond stone (25 micron) and a very special ceramic stone, made of synthetic sapphires. Although the stone will get worn, the advantage of these materials is that they will still keep their flat shape, which is important when you sharpen your knife. And, since these materials are the hardest we know of, they will sharpen any steel, even these extremely hard powder steels. You don't need any lubrication for these stone but now and then you should consider cleaning them with warm water and liquid soap. The stones might feel coarse from the start but will become smoother/better after some use. A leather pouch is included.
Upon delivery, your new DC whetstone will appear very coarse. This coarseness will disappear when the tool is put to use.
