So I've been eyeing the adjustable Gillettes, but am wondering a few things about them. Hopefully you guys can give some good advice. First, what are the diameters and length of the "Fat Boy" and the Slim handles? Second, how much cleaning do these razors require? I am used to 3 piece razors which require pretty much nothing. Seems to me that with these razors being TTO and adjustable that soapy water would totally work its way into these razors and make them pretty scummy after not very long. Thanks in advance for everybody's advice!
