Larger damage I previously leveled with the 400 stone.
For fine. and final I water the 1000/3000 stone at least one quarter of an hour, then put it on a wet sponge and the whole thing on the counter and start right away.
Again water on it and then calmly and evenly the knife on the stone move to a good sharpness is produced. The grinding sludge remains on the stone because it is part of the grinding process. In between, repeatedly rinse the knife, control, stone moisten and so on until the desired result is achieved.
Then turn, dampen and eliminate with the 3000 grit fine scratches the stone. Finally, I'm going with a 6-8000er Arkansas after cutting to the mirrors)
The results speak for themselves. The Gräwe whetstone SHARP HOME grit 1000/3000 I can recommend, it is affordable and provides good results when used as directed.
