Expert Verdict — Reviewed by the SuperArbor Pro Desk

Score the face paper against a T-square in one firm pass, snap the core back, then cut the back paper from the fold. Replace or sharpen the blade as soon as it drags, since a dull blade tears drywall paper and leaves rough edges. Keep a second knife on the cart for cutting face paper only.

Always cut away from your body and retract or sheathe the blade when the knife is not in use.
