The cross hashing on the cylinders starts out the same all over. As the cylinder wears the hashing begins to dissappear. The greatest wear is near the top of the cylinder where the upper compression ring lives. If you can feel a ridge with your fingernail at the top of the cylinder where the hash marks have thined and then gets thick again you have too much wear to use the cylinders without honing them. If your cylinders are biral (they should be) then you can hone them easily. They don't have a coating to go through.
