I thought Doug posted that it is supposed to be 30 degrees from the factory, which would correspond to one of the settings on your sharpmaker. But I would expect some variation from knife to knife. I am sure that whatever method is working with your Delica will also be fine for the RSK. The sharpmaker is relatively foolproof if you follow the directions.

The one variation I make is to only use the flat sides of the stones. This helps keep the blade tip pointy.
