Fallkniven Stones (DC3 and DC4)
Some of you may have gotten one of the more recent stones like I have. One of my DC3s came with the ceramic about 1/8" too short on both ends and there were saw marks (like concentric circles) on the ceramic side that gave it a sort of serrated appearance. This makes it VERY hard to get a clean edge on the finish side.
Here's a quick trick to fix the texture problem.
If you've got another Fallkniven stone just rub the rough ceramic side on the diamond plate in a circular motion (like you're lapping a water stone) and use plenty of water. Don't push down too hard and be patient. In just a couple of minutes you'll have smoothed out the ceramic side and it'll also open the pores of the material to really help with your final sharpening.
I tried lapping the ceramic on a piece of worn sanding belt over glass but the ceramic is too hard for anything but diamond.
It seems like it cleaned up the diamond plate too.
At first I was really disappointed with the quality of the last batch of stones but in my small handful I received one that was a problem and one more with an ill-fitting ceramic side. The lapping fix took care of the functional problem so the rest is purely aesthetic.
