Further Information

The Fallkniven DC4 Diamond Ceramic Whetstone is a popular combination whetstone made for accurate knife sharpening in the field. Small and lightweight, the DC4 is ideal for keeping on you when travelling by foot. For a more compact whetstone, take a look at the Fallkniven DC3 or, for a larger whetstone, the Fallkniven DC521.

The DC4 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 DC4 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 DC4 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.

After sharpening your knife, Woodlore recommend the use of Ice Bear Camellia Oil to protect the blade from rust and corrosion.

  Great size for taking with you when camping and the leather pouch for storage is a bonus. Should last a good while!

  This is a great bit of kit and is essential for keeping your blades sharp in the field. Don't get me wrong - it could never replace my full size whetstones but they are too heavy and fussy to take on trips out. Whilst I hope I never need to use the diamond side, it's comforting to know you have the tools to get rid of any nicks if you are unlucky (or careless) to get one.

  I'm very surprised. The diamond side takes of steel very fast. The other side makes a razor sharp edge. Its a good idea to strip the knife over some leather (inside of a belt) after sharpening. It works very good and vast on small folding knives too.

  Incredibly handy, small enough to fit in a pocket and produces a lovely sharp blade.
