Now I am really confused. If you're finishing on a 20 or 30k stone, do I have to touch up my razor on that high grit to make any difference? So, in general, to touch-up a razor one needs to go back to the highest grit stone it was finished on?

Let me be clear what I'm trying for here. I have little to no interest in honing from start to finish. Not yet anyway. I have one razor, A Boker King Cutter. My mane interest is in using this razor daily, which I do, and aintaining the edge as long as possible before having to send it to get honed agian. When I do send it out, do I need to know the Honmeister's finishing set-up so that I can duplicate it on touch-ups? Or is my little barber hone good enough? Or do I need to get a higher grit hone to touch-up?
