I have it in my pocket again today.
As a small pocket tool to cut everyday stuff it is perfect.
Its nice and smooth (no rough spots) the blade is firm and sharpens easy.
I dont consider myself very good at sharpening all I did was a 10 careful strokes on either side of a DC4.
The DC4 by the way I highly recommend thee latest version has a leather strop side on the pouch.
"The DC4 sharpener is a whetstone with a combination of diamond and ceramic that will handle all your sharpening needs. The DC4 whetstone consist of a fine diamond stone and a very special ceramic stone, made of synthetic sapphires. The advantage of these materials, although they get worn, will still keep their flat shape this is important when you sharpen your knife. And, since these materials are the hardest we know of, they will sharpen any steel, even these extremely hard powder steels. You don’t need any lubrication for these stone but now and then you should consider cleaning them with warm water and liquid soap. The stones might feel coarse from the start but will become smoother/better after some use. A leather pouch is included".
How to use your DC whetstone
If your knife is dull, we advise you to start with the diamond stone. After restoring the edge to original shape, de-burr the edge lightly with the ceramic stone in order to get a razor-sharp edge. Use no oil or water. Start by laying the blade flat on the stone, raise the blade spine approx. the thickness of the blade, and start moving the knife in circular motions.
