Carl
On a rotary trimmer the blade is a consumable and it is also the feature. Straight blades give a clean cut, while perforating and scoring blades change what the edge does afterwards, and they swap into the same machine. Cutting length matters more than the base size, since a trimmer rated below your sheet forces two passes and a visible join. Carl is an ACCO MATS brand. See guillotines, blades and punches.
