Pretty much North-South until I get to my throat. There, about mid-way between the corner of my jaws (below ears) & my chin, everything is East-West, at slightly varying angles. I start with a high to low stroke, then reverse to a low to high (if I want *no stubble*). I do have slight variances on my chin, below the corners of my mouth. And just below the jawbone, same mid-way point stated above, I have the dickens of a time smoothing it out as well. If I persist, I'll get a bit of irritation, but my '41 Ranger Tech with a Voskhod gives me the best performance.
Cheeks: From inner cheekbone down and slightly back. Jawline: Tip of chin to back of head along jawline Neck: Seems to run from point of chin down in front, and side run diagonally towards the back of the neck
