After following all of the pros and cons of different flattening stones on this board, I decided to try the ever popular D8C.
Got and went to work on a few bad blades. It did good. Then tried lapping my JNat and Nortons and before long, the D8C was smooth as smooth as my strop. Cleaning it is also a bear. The thing developed a black shadow around the middle of the hone and I took for granted it was metal from honing some blades. I tried everything I could think of to clean it. But the bottom line is, I don't know how a diamond hone could get so smooth after just a couple weeks. It's like honing on a Norton 8000. Can anyone give me the scoop of what I've dome wrong? I do clean after each use by the way. All comments and suggestions welcome.
