Fiskars Circle Cutter makes it easy to cut circles on paper or cardstock, perfect for creating windows on homemade cards, scrapbook pages and more. Cut circles from 1" to 8" with no preset increments for crafting versatility. The clear cutting mechanism and needle-point blade ensure precise alignment with your project needs while a gripping foot prevents slippage while cutter is in use. To use, select the circle size you need by turning the lock wheel clockwise to loosen the cutting arm. Retighten the lock wheel once desired circle diameter is reached to secure cutting arm. Next, align the circle cutter with your project and apply pressure to the control nob with your non-dominant hand. With your dominant hand, apply light pressure to the cutting arm and move it in a circle around the cutting mechanism. For best results, always use a Fiskars self-healing cutting mat. Circle Cutter cut capacity is intended for 1 sheet of 20# paper (75 gsm) or 1 sheet of 80# cardstock (218 gsm).
