Nihonivs the Pompeii blade is the easiest to do and will help you understand how a grinder works the straight edge gives you a guide which will be easier to follow. The curves of a Mainz the blade geometry from apex to edge changes down the blade and the trick is to keep the blade flowing and look flat all its entire length.

This is a apex blade it has a high centre then the blade is flat from this point right up to the cutting edge.

The one on the left is the leaf profile I hope this shows
The trick is to have a centre line drawen down the blade for both profiles and dont grind over the line , work up to it then gentley blend it in to the rest of the blade.
