With this cutter you can easily cut paper strait using the roll as a liner, works also for a flat sheet. Cut one section of the box cutter knife blade. The blade seating is quite thigh. Lock the blade in (use e.g. screwdriver mind your fingers), press on the side of the blade so that you hear a snap. After the assembly the unit is quite finger safe.
