My Dad passed away 7 years ago. He use to shave with a double edge but at that time, I wasn't yet "into" safety razor shaving. I' ve only been using a safety razor for a month now and last week was visiting with my Mom. I asked her if she still had Dad's shaving paraphernalia. Long story short, I now have my Dad's Gillette Fatboy razor! It needs a real good cleaning, but I think it will be usable. One question: I can't get the adjuster to budge. Is there a trick or do I need to use a wrench and some lube on it? Any help would be appreciated. Thanks in advance.
