In all the honing videos I have watched, the blade is drawn diagonally down and across the stone. This takes the heel off the hone very early, leaving progressively more time on the hone right up to the toe, which stays on the hone all the way through the stroke. Won't this cause the heel of the blade to be much less refined than the toe? Even worse, will this cause the toe to wear faster than the heel, causing the dreaded "smile"? FYI: I am a complete newbie.
