FISKARS-TripleTrack Refill Blade Carriages: Cutting & Scoring Blades. Designed to work with Fiskars TripleTrack Personal Paper Trimmers only. The cutting blade (orange) cuts up to five sheets of 20lb paper or two sheets of heavier cardstock and the scoring blade (black) neatly creases paper for a professional look.
