ABSTRACT:
A tool for use with a type of bookbinding strips wherein one strip is formed with bendable studs and the second strip is formed with holes and grooves in one surface extending away from the holes. The grooves are preferably formed with overhanging top longitudinal edges so that the studs, after passing through holes in the pages of the book and the holes in the second strip may be bent down into the grooves, snapping under the overhanging edges. The tool of this invention may be gripped at one end and drawn along the top of the second strip, bending the studs down into the channel. For this purpose, the end is curved and also recessed to receive the second strip. To bend the studs upward to debind the book, the tool is also formed with a shallow slot having a protrusion therein formed on one or opposite sides with depressions into which the pointed end of a stud may fit. By pulling the tool away from the second strip, the stud is bent upward to approximately its original position.
