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.

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.
