How to scratch & break:

Place a plastic board on a flat surface and take straight strokes to make a score, deep enough to break by hand. Approximately one-third depth of the plastic board will be the rough standard.
Snap off downward by hand along the score.
Clean cut surface with the unsharpened edge, if necessary.
