Cutting Styrofoam

I've noticed a "grain" in Styrofoam. I suspect it extruded and that stretches out the polymer in the polystrene. When you cut Styrofoam with a dull blade, it creates chunks more readily if you cut across the grain.

The moral?
Cut only with a sharp blade and only along the grain if you absolutely must use that dull blade once more.
