Ok I have a question on the different grinds. I looked on wiki and elsewhere that shows the different grinds, but haven't been able to find much on how they differ when it comes to the shave. Somewhere said something like a full hollowgrind allows the edge to flex for a closer shave. I'm assuming the flexing would also mean more chances to nick yourself as well. And wedge or 1/4 hollow being better for thick and/or course hair.
