Hello mates,
I have a W&B 7/8 wedge on the way and was curious if the shave technique changes for a smiling wedge. I currently use a Hart Steel 7/8 rounded which I'm starting to shave rather decent with now. When shaving the sides of the face and keeping a somewhat constant 30 degree angle, I can feel the entire edge in contact with the skin, cutting hair.

Looking at the smiling blade, it seems to me the entire razor's edge will not be in contact with the skin. I'm curious if that is true. Also, is there any advantage gained or lost by using a smiling wedge? Thanks.
