Abstract: A tape rule holder formed from two die cut flat pieces of heavy duty, top grain saddle leather. The back piece includes belt slots in its upper section. The front piece or pocket-forming member is configured in its flat pre-assembly form with peripheral side rivet areas and a bottom rivet area each defined by a fold line. Approximately mid-way of each side rivet area of the front piece is a "v" notch. Upon rivet assembly of the front pocket-forming piece to the back piece, with the front piece bowed outwardly to form a tape rule pocket and the "v" notches of the side rivet areas closed, the resulting tape rule pocket includes side walls using inwardly projecting pressure detent ridges which together grip a tape rule inserted into the pocket of the holder and maintain the tape rule therein against accidental dislodgement.
