Thread: What is the highest grit you have used on a stone?

Lapping only influences the surface flatness to make sure the blade is flat on the hone. At the dimensions of a razor blade, scratch lines in the hone surface don't matter anything.

I would agree except for with arkansas stones, where the "binder" is also the abrasive.
