I would recommend 1000,2000 and 5000 grit. Get a honing guide so you get perfect angle and straight bevel. Find yourself a good sharpening station for better result and safety. Also, remember to get a diamond stone to keep your stones flat.
Similarly, can I sharpen a chisel with sandpaper?
While you can use a bench grinder or sharpening stone to sharpen a dull chisel, a piece of sandpaper on a flat surface can be used to get the job done, too.
Correspondingly, what are the grinding and honing angles when sharpening planes and chisels? The primary bevel for chisels and plane blades is normally 25 degrees (a time-tested angle). If you look at the blade diagram above its perfectly acceptable, from a sharpness perspective, to hone the primary bevel flat and hone the back of the blade flat and where these two meet you can achieve a sharp cutting edge.
