I am just a little lost (ok really lost) and have not found anything that explains the real difference between Straight Bar vs. Open Comb. I am trying to figure out as someone with a beard and moustache which better serves me as well as what is the real difference. I have looked through the FAQ and other place where I thought I should find the information. If I am processing everything I reading correctly it would sound as if HD Hefty Long Handle Double Edge Razor - Straight Bar by Merkur would be a good starter for someone like me. PLEASE HELP ME!!! Thanks!
