For accurate, safe cutting, always remember to use a steel ruler or straightedge and a cutting mat. Cutting mats are made of a self-sealing sheet of plastic that can be used over and over again without damaging the tabletop. Never press too firmly in an attempt to cut right through a surface in one pass, as the blade may well slip or track off. Several light cuts in the same groove are better than a single hard one.
