Method and device for truing a razor blade

A method for truing a disposable razor blade, comprising the steps of:

• a) providing the truing device comprising:
• an elongated base portion extending along a longitudinal axis and having opposed first and second side walls, opposed first and second end walls, and a substantially planer bottom face;
• and
• a smooth top working surface portion extending between the opposed first and second end walls, wherein the smooth top working surface portion is comprised of a synthetic cultured stone material and is configured to engage at least a portion of a disposable razor blade;
• wherein the synthetic cultured stone material is comprised of a cured precursor composition, the precursor composition comprising a calcium carbonate component, a thermosetting polyester resin component, and an additive component comprising at least one additive selected from a liquid colorant, dry pigment, magnetic material, and stabilizer;
• b) applying a disposable razor blade having a longitudinal axis on to a portion of the working surface of the truing device such that the longitudinal axis of the razor blade forms an acute angle relative to the longitudinal axis of the truing device base portion;
• c) applying pressure to the razor blade so that at least a portion of the razor blade conforms to the contour of the working surface;
• and
• d) drawing the conformed razor blade of step c) along at least a portion of the working surface and in a direction along the longitudinal axis of the elongated base portion;
• wherein the method is not capable of restoring sharpness to an edge of the disposable razor blade.
