Difference between open and closed combs?
I've been thinking about picking up another DE razor sometime soon and I was wondering if anyone could help me with understanding the differences between the two in terms of shave quality.
Right now I have a Merkur 34C with a closed comb. With a new blade the thing shaves like a dream. Would there be much difference between it and say a 15C which is open combed?
I also see people talking about shimming their blades. I've never shimmed a blade but I understand a little of the reasoning behind it. I assume that an adjustable DE would be the same principle.
So since I have a good DE that I like already should I just stick with it or should I look for an open comb as well? Or maybe an adjustable butterfly opening DE? Maybe both?
