I never thought of it before but I guess there would be a subtle difference in shaving technique between a curved edge razor and a straight. I noticed that my straight edge Dovo seems to shave better than my other razors that all have a slightly curved edge. It occured to me that assuming they are somewhat equally sharp, you would have to account for the curved edge when shaving. What I am thinking is that the heel and toe of a curved blade may miss some hairs whereas a straight would pick up.
That said, a curved edge has it's advantages in some of the more contoured areas like around the apple or the upper lip...

I guess a curved just requires a few more strokes . . .

Thoughts anyone?
