I liked the question about overhoning the heel because logical thought is "I've mostly produced wear on the toe so the bevel at the heel is still nearly perfectly formed and polished. If I hone evenly then I'm bringing the toe back to perfect condition but the heel will form a wire edge." I might be wrong as to op thinking but that's my take. You will need to remove metal from the heel to bring the toe back into shape after all the "face time" with stubble has caused enough microchipping that stropping cant resolve, but its microscopic and can be done without going to a course stone. At the coursest an 8k with slurry will handle the deal. Overhoning on this scale is really not something to be concerned about. If a wire edge forms it is usually at the hands of courser stones and will actually be polished off once you hit 8k and higher. Also, Nice and even honing done periodically extends the life of a razor because it negates the need for aggressive honing. Rant complete, sorry
