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.

  Good pocket sized stone, replaced a cracked one I had for years (don't drop it!) nice coarse diamond side for dressing the edge, ceramic side is pretty fine for sharpening up. DC4 is about as small as I'd want to go, but if you're a bit more coordinated you could save a few grams with the DC3...

  Really small but adequate to sharpen a small hunting knife. Use the gold coloured side first and then the darker ceramic side to finish. The cover has a rough rear side for stropping, it's advisable to use some stropping compound. For the price, you can't argue.

  Great sharpener. Just what I was after, handy size and easy to use. I have this one and one of the Fallkniven CC4, which has an even finer ceramic surface. Together they are the perfect set.

  I've just used this once to sharpen the Mercator K55K Folding Pocket Knife and it worked very well. Ray recommends a modern fixed angle sharpener for this specifc knife, though I thought I'd get this whetstone as I can use it on a variety of knives if required. Very functional, in a lovely leather pouch and the perfect size for any jacket or trouser pocket.

  I have had the DC4 a little while and think it's a great pocket sized sharpening stone. It's useful to have around for quick maintenance. Have used it on a few knives, my Companion Heavy Duty in particular. I have also used it to restore a decent edge on an old Swiss Army Knife. I like the fact it's so portable and it is pretty straightforward, I would recommend.

  Puts a tremendous edge on dull blades with very little effort though confused why the instructions state no water is to be used as this is the very definition of a whetstone to my knowledge?...notwithstanding an excellent item and very reasonably priced for the quality!

  Pretty compact and convenient. I'm yet to get my knife shaving sharp, but I'm just learning still. It would be nice if this was a 5 inch model.

  This is my second purchase from Woodlore, and again not disappointed, the stone is lightweight and small enough to pack anywhere in your kit, and as my thumb can testify it does a very good job of sharpening my Mora. Good products and service, highly recommended, this will not be my last purchase.
