A device for use in dividing a line into a predetermined number of equal parts. The device consists of a number of identical elongated links whose ends and centers are hingedly connected to form a set of extendable lazy tongs with preferably sixteen identical pointed rods attached to the hinged ends on one side of the set of lazy tongs. A case encloses the set of lazy tongs with the pointed ends of the rods projecting out of an elongated slot along the bottom of the case. One end of the set of lazy tongs is attached to one end of the case while the other end of the set of lazy tongs is attached to a slidable shaft which extends through a second elongated slot along the side of the case. The shaft is attached to a finger operated tab slidable along the second elongated slot for moving the lazy tongs and the pointed rods so that the pointed ends of two predetermined rods lie at the ends of a line to be divided into equal parts.
