Ok this is for you old pros. Each time I buy what I think is a finer stone I just continue to hone . As in I do not kill the edge I have . I hone as I imagine one would to touch up an edge. It seems to work well enough for me. The question is should I start from the beginning? I'm always experimenting and learning so it's just something I haven't asked yet. My example would be that I had some razors that have coticule edge. When I got my Welsh slate I just hones on slate thinking the grit was higher. Now some slate edges I have I have taken to my new Escher. I haven't noticed any negative so far. Just throwing it out there to get some feedback or direction. It's always tricky asking opinions here but I am the type to ask. Thanks for any comments.
