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.

  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.

  I decided to purchase from Woodlore because I trusted that they would deliver promptly and that the item would be of high quality. Ten out of ten on both accounts. I bought the DC4 as a Christmas gift, it was delivered quickly and very well packaged. Although I haven't personally used the item, my Dad has and is over the moon with it. It provides a quick and simple way for him to sharpen his knife on the go, without needing to pre-soak his waterstones or get his fingers covered in oil on his oil stone. The carry case provides a good level of protection for the stone and the small size makes it easy to store and carry around.

  I bought this for a close friend as a present, as I love the one I bought over 5 years ago (if my memory serves me right). The ceramic side has some changes, it is a thicker ceramic and the color of the ceramic is a very dark grey (as opposed to the dark brown in my older one). I am confident this will accompany my dear friend in his adventures in the woods and serve him as well as mine serves me. I'd also like to thank the guys and gals tending the shop for a very quick order and shipping process.

  Fantastic little double sided whetstone that comes in a leather pouch for storage. Bought it to go in my work rucksack to use with both fixed and foldable knives. Got my Swiss Army Knife blades to razor sharpness, enough to dry shave the hairs off your arm - never underestimate how useful a sharp knife is, even I was surprised how good the edge is. Cleans easily enough in warm water and a little hand soap, just make sure you dry it thoroughly and set it on some newspaper (or similar) to draw the extra moisture out of the stone as it will hold a little. My only criticism is that it is thin and any knife with a thicker handle, you may struggle to get you blade to the right angle to sharpen up and so a stand with a grippy surface would be a good investment to accompany it. I used a 10cm thick book so my hand could move with ease, but this is to be used in the field and this can be easily overcome. To summarise, a great product and would buy again (if ever needed) and a hearty recommendation.

  Bought this to keep my knife sharp when out. More than happy with it. It gives a sharp edge every time.
