I'm not sure it it's possible to line them up front and back.
You gott'a use 'em, unless you have a serious accident they won't catch any harm. I've been using my 1915 copy that I got off Chris for 13 years now and it still looks as though it's never been used.
The anodising on this last one is a new type Chris has started using, it's call "hard anodising" and is said to be very scratch resistant.
