ABSTRACT:
A slit is cut along the nesting fold line of a doubly folded folio format newspaper in order to minimize the buckling of the paper when the pages are turned. The slit has a length of between about 2 and 5 inches and is located so as to be bisected by the secondary fold line of the newspaper which is perpendicularly disposed to the nesting fold line. A specialized tool is provided for manually cutting the slit.
