The Fallkniven DC521 Diamond Ceramic Benchstone is a popular combination whetstone made for accurate knife sharpening. It is the largest sharpening stone in the Fallkniven range, and as such is best suited to sharpening while at camp or at home. For a more portable whetstone, take a look at the Fallkniven DC3 or Fallkniven DC4.
The DC521 features two different sharpening surfaces; one is a fine diamond whetstone of 25 micron, while the other is a fine ceramic whetstone, made of synthetic sapphires. If your knife is dull, it is recommended that you begin by using the diamond side, which will restore the wedge shape of the blade's edge. Following this, you can de-burr the edge lightly using the ceramic side, in order to get a razor-sharp edge.
The DC521 is a very low-maintenance tool in the sense that it can be used dry, without the need for any lubrication from oil or water. Every now and then, it is recommended that you simply clean the stone in warm, soapy water.
A major benefit of the DC521 is that, while the stone will become worn over time, the sharpening surfaces will remain flat, helping to aid efficient sharpening. The supremely strong surfaces can be used to sharpen any type of steel, including hard powder steels. At first, the sharpening surfaces may feel overly coarse, but this initial roughness will diminish after use.
