ABSTRACT:
An anti-fraud string cutter for a coin telephone instrument having a serpentine coin path. The string cutter is fabricated as a stack of notched, slit, sheet metal plates having alternately off-set flat and wavy teeth which are adapted to snag and cut, between adjacent ones of the plates, any string threaded through said coin path by a fraudulent user. String cutters are advantageously to be mounted adjacent to one of the cusps of the serpentine path and above the coin return hopper.
