I'm still a bit of a newbie at straights. My shaves are getting better, but I'm still reading and watching pretty much everything I can get my hands on to further refine my skills. In my quest, I came across two pieces of data that I'm either interpreting wrong or just plain having a hard time reconciling.
First, from the SRP ShaveWiki, is the picture below of blade angles for WTG, XTG and ATG passes. According to this, the best angle for an ATG pass is about 5 degrees.
Second is this thread on razor dimensions that, if I read it right, as a byproduct seems to indicate that the angle of a razor from the edge to the spine is around 15 to 17 degrees.
So, if I'm reading both of these right, on an ATG pass, you should actually push the spine into your face a bit? That doesn't sound right. I must have something wrong. Can someone point out what I've missed?
