A tape-measure device having elements for measuring and/or marking/cutting an object, includes a tape, a shell (3) with a reel, an opening (5) enabling the tape (2) to pass through the shell wall, an end piece (6) attached to the distal end of the tape, a stop button (7) for the reel for blocking the tape or for enabling the rolling/unrolling of the tape. The elements include a guide shoulder (8) formed on the shell, a guide opening (9) at the end piece for the removable insertion of the end of a marking/cutting tool, and a sliding surface (60) for the end piece for translatably engaging the surface of the object to mark/cut the object using one of the surfaces thereof when the guide shoulder is simultaneously slid along an edge of the object and the end piece of the tape against the surface of the object to be marked/cut.
