This might sound like a stupid question but oh well! Anyone have a good way to "mark" the razor so that one can tell the difference between the edges? In other words, I'd like to use one side of the double edge until it's not sharp enough to use anymore, then move to the other side so I get maximum use from the blade. I will be using a Merkur HD that I'm about to put my order in for..
Thanks!
