I got an old genco razor from a friend. The blade seems to be in great shape (no major rust, no spots, scales are fine). the only problem is that the edge is a little wavy where it has slowely deteriorated. what's the best way to straighten it out and reset the bevel? I was thinking about using a low grit stone with straight passes to straighten it out. Is this the right decidion, or is there something else I should be doing? Thanks in advice for the advice!
