A method of forming a working electrical discharge machining electrode for creating an injection mold having a gear form. A cutter tool having a single cutting surface is formed, and the cutter tool is used to machine the electrode to form a tooth surface having the same curvature as the single cutting surface. In machining the electrode, a longitudinal axis of the cutter tool is substantially perpendicular to a longitudinal axis of an EDM electrode blank.
