I have been experimenting with my Karve CB and in general, I think the relatively straight blade (at least compared to my Fatips) seems to encourage irritation and the odd ingrown hair. Something that never happens when I shave exclusively with the Fatips (even they are quite a bit more aggressive than even the D plate). Beyond that, I keep nicking myself with the exposed blade tabs on the side of my neck when I shave under and along my chin. I will therefore be unloading this razor very soon. It shaves great in large, even areas like my cheeks, upper lip and lower lip, but struggles to deal with the curved areas of my face like the jowl and neck.
