Abstract A device for sharpening a tailor''s chalk is formed from a unitary sheet having a longitudinal medial slot terminating at one or both ends in side edges converging to a sharp apex and includes a flat horizontal base panel and a first vertical panel between the ends of the base panel and a second panel extending between the top of the first panel and either the bottom of the first panel or an end edge of the base panel. The first panel has a vertical slot extending from its top edge and terminating in side edges terminating in an apex at the base panel. The second panel is either flat and superimposed on and similar to the first panel or an inclined slotted panel extending between the first panel top edge and the base panel end edge or of angular configuration including a horizontal slotted top section and a vertical end section joining the base panel end edge.

A chalk sharpening device integrally formed of a unitary sheet and comprising a horizontal flat base panel having a transverse front end edge, a first panel extending vertically from said base panel front edge and terminating in a transverse top edge, a second panel extending horizontally rearwardly from said first panel top edge and terminating in a transverse rear edge, a third panel depending from said second panel rear edge to said base panel and having a bottom transverse edge and a fourth panel extending forwardly from said third panel bottom edge to said first panel and being superimposed on said base panel, said first and third panels having similar slots formed therein, each of said slots including transversely spaced parallel vertical side edges depending from the top edges of said first and third panels and terminating at their bottoms in downwardly converging side edges defining chalk shaving and shaping sections, and said second panel having a longitudinal slot formed therein extending the full length of said second panel and having side edges joining corresponding vertical side edges of saId slots in said first and third panels.
