I have a Gillette Knack in the mail headed my way soon. The one I'm getting is a 1968 and the seller has used it twice and said because of its condition it could be the only two times its ever been used. It comes in the case with instructions and maybe a pack of blades but not sure. My question is more about how this razor shaves and performs. It is going to be a gift to my wife who recently got into DE shaving with a Parker 29L, which seems to be a copy of the Lady Gillette. The Parker was poor quality and I had to realign the silo doors and it still seems to have uneven blade reveal. Hence the Gillette Knack. I have a 1970 super adjustable and think its a quality piece and hope this is too. Any info would be great.
