ABSTRACT:
To precisely scratch a sheet of glass and then tap it to sever it into two separate pieces of glass while maintaining perpendicularity of the glass cutter handle to the glass surface, without twisting the wrist or arm while applying downward pressure, the rigid handle of this glass cutter approximately midway between the cutting wheel and the upper servering hammer portion is provided with a rigid widened portion through which the user's index finger is inserted during the application by it of downward pressure for scratching the glass. This apertured rigid widened portion is then grasped by the fingers to assist and precisely guide the cutter handle while tapping the scratched glass with the hammer head to separate the glass portions on opposite sides of the scratch.
