An improved tape measurement marking device attached to a measuring tape or built into a conventional tape housing. The device includes a sighting plane for alignment with the desired measurement mark on the tape; a structure for receiving and directing a hammer blow to a marking blade; and a marking blade that produces a dimensionless mark precisely at the desired measurement, a void to place the tape hook in, the void having an edge to hook the tape onto, the edge coinciding with the desired measurement mark; when the device is used on an existing tape, mechanisms for assembling, sliding, and clamping it on the tape are included.

A precision marking device, for use with an extensible measuring tape having a tape hook secured at a free end and measurement marks parallel to said hook comprising: (a) a means for sliding said marking device along said tape to a desired measurement on said tape; (b) an indentation blade attached to said means for sliding; (c) a means for sighting attached to said means for sliding for sighting said desired measurement and aligning said indentation blade with said desired measurement on said tape; (d) a means for locking attached to said means for sliding for locking said marking device on said tape at said desired measurement on said tape; (e) a structure comprising an impact target on said structure connecting said target to said blade, said structure capable of absorbing and directing the force of a blow to said blade; (f) said indentation blade configured so that when said indentation blade is locked at said desired measurement on said tape and absorbs said blow said blade produces a groove in a surface of a work piece being measured, a wall of said groove being formed perpendicular to the surface of said work piece, said wall and said surface forming an edge coinciding with said desired measurement on said tape, said groove being capable of allowing said tape hook to be inserted and hooked onto said edge, thereby providing a precise starting location and holding means for said tape hook, by applying tension in said tape, for the next measurement.
