Now I may be a beginner woodworker but I was a Senior Research Engineer at Norton company way back when and I taught in their school of grinding. Here's some advice.
As with all cutting tools , if you keep up with it with frequent touch ups its easy but if you let them go a long time , resharpening is a bitch. Be careful with the grinding. Don't overheat the edge or it will loose its temper and just not be durable. Best bet where possible is a dribble of water over the grinding wheel and edge and a slow RPM grinder.
I agree a fine grit is best for precision grinding.
