I have been wetshaving for almost five years, and usually get good, BBS shaves. But I have always struggled with an area under my chin where my hair grain's direction changes. This stripe is about one inch long and half an inche wide, and it is a continental divide of sorts. To its left, the hair grows in one direction (left to right), and to its right it grows in another direction (right to left). I have a coarse beard and yet can easily shave on either side of the "continental divide." But in the "continental divide" area proper (where the hair grows in almost every direction), I always have trouble. I usually need several passes to make it BBS, which can lead to some irritation, or I cannot shave as close as I wish. Does anyone have words of wisdom on what to do here?
