I'm just getting started with honing and would appreciate somehelp. I plan on using Naniwa super stones to start. My first step is to flatten the stones when I receive them. I was going to flatten them on polished tile and wet/dry paper. A woodworker friend advised that I use sanding screens. They are intended for drywall and last longer because they can be washed and re-used. And the open mesh reduces loading. Has anyone tried this? Also, I would like to know what grit to use on the Naniwas. Is it a progression, or do I just need one grit? I will be flattening a 1k, 5k, 8k and 12k.
