My daughter found me a near mint G3 adjustable Fatty. Tried it this evening with a Treet Black beauty (already used a few times). Had the razor on 4 (it came to me like that), but the shave was far from close. Perhaps the Treet had already lost its edge, as I can recall shaving with my slim adjustable on 4 or 5 gives nice results. Will try again with a new blade.
