Been wet shaving for about 9 years now and finally tried my first FB that I purchased from a member on here. Can’t believe I’ve missed out as man this thing is nice. Had been coated by North Shore razors so not only does it look stunnin, but it’s shaves amazing. I haven’t tried it, but I’m guessing you can’t change the setting with the blade in there. Is it suggested to only turn setting with doors open and blade out or can you change setting with doors but and no blade in?
