Picked up a 68 Gillette Slim Adjustable ( Christmas gift for my son)and got a really what I would call a good deal, anyway the 1-9 adjustment clicks very sharply at each point and the doors open/close very smoothly but that last 1/4 turn to snug everything up seems really, really tight. I can get it done but it takes a lot more force than my F3 Fatboy and I am curious if this is normal like maybe it was not used much as it looks pristine and was in a case with instructions and blades.
And if not normal how would you loosen it up ?
