1. A process for honing at least one edge on a workpiece comprising the steps of:

  • placing a workpiece in a fixture;

    rotating an abrasive brush about an axis of rotation, the abrasive brush including a plurality of abrasive bristles which define a volume;

    positioning the workpiece edge relative to the axis of rotation of the abrasive brush such that the workpiece edge to be honed is substantially parallel to the axis of rotation;

    positioning the workpiece edge to be honed at a circumferential location relative to the axis of rotation of the abrasive brush, the circumferential position being selected to provide a desired hone shape;

    positioning the workpiece edge to be honed at a radial distance from the axis of rotation of the abrasive brush, the distance being less than the radial length of the bristles of the abrasive brush; and

    translating the workpiece along a path substantially parallel to the axis of rotation of the abrasive brush such that the workpiece edge passes through at least a portion of the volume of the abrasive brush.
