Abstract: A retractable tape measure of basically conventional design is provided and includes a tape spool hub projecting slightly outwardly of one side of the tape measure housing. A conventional blade-type belt clip includes a free end portion which overlies the hub for frictional engagement therewith upon inward deflection of the clip free end portion by inward finger pressure applied to the outer side thereof. The abutment flange carried by the free end of the tape has the usual opening formed therethrough (previously provided to receive a brad or tack) and a sharp pointed hook is shiftably supported from the tape free end and projectable through the opening. The pointed hook may be manually forced through the opening for penetrating a penetrable surface against which the tape end abutment flange is abutted. The housing of the tape measure includes a spool mounted chalk line and internal opposing pads between which the chalk line passes for wiping excess chalk therefrom.
