I leave the pages uncut on a number of the journals I bind, giving the pleasure of opening them to their recipient. The pages are not printed, but are dyed as whole sheets and then folded down. Technically they are 'unopened', but also uncut in that they have a torn edge. To open the pages use a dull knife or old fashioned letter opener, not a finger or pencil. My favorite tool is this old piece of cutlery. Slip it into the fold at the edge of the page, with the blade flat against the surface of the page. "Cut with a dull knife held parallel to the plane of the paper. Cut out, away from the book," instructs Jane Greenfield in The Care of Fine Books.
