The 12" x 12" Rotary Cutter and Ruler from Fiskars is a must-have for anyone who wants to cut perfect shapes from fabric. The 45 mm spring-action blade makes clean cuts through multiple layers of fabric, and the ergonomic blade carriage makes cutting smooth and easy. The attached ruler has a bold 12" x 12" grid printed on both sides for right- or left-handed use. Highlighted numbers provide excellent visibility on light or dark fabric. The rail design prevents lint build-up, while the no-touch magnetic system makes blade change safe and easy. A carrying handle makes it convenient to transport. Extra blades and the magnetic blade change tool are sold separately (f-195120-1001).
