Pencils, Continued Regular office The regular office pencil sharpener sharpens the pencil lead to a conical pencil point. It both shaves, away the wooden casing and shapes the lead core. sharpener Although a conical point is excellent for drawing thin, precise lines, you must maintain point consistency by sharpening often. Draftsman’s pencil sharpener Unlike the regular office sharpener, the draftsman’s sharpener does not shave away the wood case around the lead core. The draftsman’s sharpener shapes only the lead. Expose the lead core approximately 3/8 inch by either cutting away the wood with a knife or releasing the lead from the mechanical pencil handle. Insert the lead into the draftsman’s pencil sharpener and rotate the sharpener top. This contacts the pencil lead with a replaceable sandpaper tube inside the sharpener and creates a conical point.
