I have the jaws. It's a very efficient razor, but I also find it harsh/rough if that makes sense. It's not a particularly smooth razor for me. How does the regular 0.84 open comb compare to it? is it just as aggressive/harsh as the jaws or is it a bit milder than the jaws? looking for comparison of the 2 razors and if I should buy a regular 0.84 open comb.
