nicked corner
The corner of the cover of a book which has the
turn-in on the fore edge overlapping the turn-in
at head and tail. This type of corner is made by
cutting the covering material at a 45° angle
at a distance of about three times the thickness
of the board from the corner. The head and tail
are turned over first, followed by the fore edge.
A small tuck forms a smooth edge at the corner.
