My silvertip got here today. Gonna test that bad boy out in the morning.
I've found that I seem to have a better angle starting at the top of my head and moving down to the neck. Back of my head does present a bit of a steeper challenge and it seems like I can't always get a perfect shave back there. I have a lot of scars back there though.
I also have scars in the back from previous bouts with ingrown hairs. But tilting my head (putting chin on chest) helped a ton! Getting smooth shaves back there now!
