A measuring and scribing device having a "clam shell" housing (1), having a forward end (9), a rearward end, an upper end, and having a lower end. Within the housing is mounted a spirally wound alternately forwardly extendable and rearwardly retractable measuring tape (2). Along the rear wall (11) of the housing is mounted an alternately downwardly extendable and upwardly retractable surface scribing implement (5). The surface scribing implement is upwardly spring biased to a safe position within the housing. An operative mechanical linkage between a hook end (4) of the measuring tap and a latch for holding the scribing implement in an extended position, allows release of the latch upon retraction of the tape, automatically retracting the surface scribing implement upon retraction of the tape.
