As someone who works metals every working day I would have to disagree with some of what has been mentioned. For one thing if you rub an abrasive on some thing it wears....period. If you rub it more it wears more. Now if you hone with the X patern over time it will cause more wear to the toe than the heel. The X patern however creates a better edge for many people and is how you get a uniform edge on a narrow hone. Barbers while they cared for their razors could replace them and didn't treat them the same way we do. To think that most of the old worn razors have more toe wear because they honed improperly might be wrong as a good many of them were from barbers.

Hey no matter what we do we wear down or blades.Thank the fates that we have people making new ones for us.
