The grain on both sides is very fine and is good only for new or extremely well preserved blade (ie already really sharp knives of keeping sharpness). If you handled the first time with water stones or if the blades are somewhat neglected, working with this stone is believed to be quite frustrating (better suited to start with is a combination of the order 800/2000).
Tip: If you start with it, should be should look at introducing a few videos on Youtube. What then helps tremendously is a simple thread counter or a pocket microscope (approx 20-40fach magnification, something there for kids here on Amazon, the term "Mini Zoom Microscope" by about 10 EUR), because it helps tremendously when sharpening when you actually looks like the cutting edge looks and what effect it has, what you have just done with the stone.
Even finer grit not really need. There does the soft back of an old leather belt or a cheaper Strop (cowhide enough the diameter of the cutting along without drawing paste only on the rough / soft back away).
