I am honing a 5/8 full hollow and would appreciate some advice about how to hone it. It has a slight smile in the spine; at the edge it is straight. There is some hone wear in the spine, more in the middle. I have honed it up to 4K on the Norton. I am using one layer of tape on the spine. It needs a little more on the toe. I'm wondering with the hone wear on the spine how I would continue with this razor; do I need to even out the hone wear and if so what is the way to do this?

Thanks
