I have read somewhere that not all Coticules are equally suitable for razor honing. Is this true?
Is there a difference between "Vintage" Coticules and recently mined ones?
What size Coticule should I buy to hone razors?
Do I really need a Coticule for sharpening a straight razor?
How often do I need to "lap" my Coticule?
What's the deal on "Kosher" Coticules? Do they really perform better than the rest of them?
What's the "grit" rating of a Coticule hone?
What is pre-dulling a razor? What is the purpose of it?
