Recently, I spent some time looking for a new knife sharpener to use when I am out in the woods. I wanted something compact, lightweight, and capable. After spending some time looking over various options, I settled on the Fallkniven DC4. At just under 4″ by 1 1/4″, it is certainly compact and it is quite light at only 3.7 ounces. I’ll share more about what makes it so capable later in the review.
The DC4 comes with a leather slip cover.
The previous sharpener that I was using utilized only diamond abrasives to hone the edge. The diamond abrasive cut quickly but it didn’t leave the edge very refined. In order to refine an edge, you need a fine sharpening stone or a leather strop. A quality whetstone or strop will polish the edge instead of just cutting the material.
The Fallkniven DC4 solved a problem for me. It features a diamond stone on one side and a fine whetstone on the other. This combination of sharpening surfaces gives you the quick cutting performance of a diamond abrasive and the ability to refine your edge on a whetstone. The DC4 also comes in a leather pouch that is not only useful for protecting the stone, but also for stropping the edge of your knife to put a final polish on it.
The diamond side of the DC4 makes short work of very dull edges.
The DC4 is simple to use. It does not require any water or oil, but it would be a good idea to clean the surfaces periodically with soap and water. If your edge is very dull, you start with the diamond abrasive. It removes metal relatively quickly so that you can reset the edge of the knife. Once you are happy with your progress, you can move onto the fine whetstone which helps refine the somewhat rough edge that diamond hones can leave. Additionally, if you want to refine the edge even further, you can use the leather cover of the DC4 to strop your edge. If your edge just needs a touch up, you can start with the whetstone or even just strop it on the leather cover.
Fallkniven does not advertise the leather cover as a strop but it actually works very well. Just put the DC4 in the cover so that you have a rigid backing and pull the edge across the surface of the leather with the edge trailing (the opposite of how you would typically sharpen, edge first). The cover has Fallkniven’s maker’s mark embossed on one side so you will want to use the opposite smooth side of the leather.
The fine whetstone side of the DC4 refines the edge and is great for quickly touching up your edge.
I was disappointed initially with how coarse the “fine” whetstone was. However, like the Fallkniven website says, it has become much more smooth over time. Mine is already quite smooth and it is getting smoother with each use.
The Fallkniven DC4 is a compact, lightweight, and capable all-in-one solution for keeping your knives sharp in the outdoors. In one small, slim package you have the ability to rehab a very dull edge, touch up, and even refine an already sharp edge. It is extremely versatile and it has become a fixture in my hiking, hunting, and even my every day carry pack.
The rust resistant properties of the Dragonfly2 make it very resistant to the problems that come from a lack of maintenance. That, coupled with the compact size, make the Dragonfly2 a great choice for a knife that will be kept in a small survival kit, car kit, or any other kind of kit that will be carried often, used once in a while, and maintained infrequently.
