It's been almost exactly a year now since my first straight razor shave and I, by no means, consider myself an expert at this point. But I want to start branching out a bit to experience more. I've been considering a DE for quite some time now to use when I travel and when I need a quick shave. (I still like to take my time with the straight and enjoy the experience)

My main question, which I'm sure has been explained in the past (as well as just about every other question a wet shaver might have), is regarding "aggressiveness." I see this term used quite a bit when trolling through the DE section. Can someone maybe explain a bit more to me what is meant by this terminology? I'm not sure if it means more direct contact with the blade or if it means something regarding the head that some prefer and some do not (similar to the grind of a straight).

Of course, I'm looking for the closest shave possible so I'm game for a more aggressive DE if that will be the result, but I want to be sure I'm interpreting this correctly.

For reference, I'm going back and forth between the Muhle R89, R41, and the EJ 89L
