If the razor needs bevel work you really need to send it out to someone. It's quite a job. If the bevel is OK and you need basic honing the idea is to do pretty much all the honing on the side you will shave with. You use back and forth strokes using downward pressure on the razor. The trick is to know how much pressure to use as you progress. You can also use diamond pasted strops if you don't need too much work.
