I have the pinking blade and use it all the time for fraying type fabrics. Plus use it all the time for apparel fabrics as I like how the seams look pinked. I keep an extra blade sitting around so never run out when I need it most. Also picked up a blade that puts slits in fabrics such as fleece for when you want to put them together with yarn. Works well with any type of fabric that does not split apart such as leather, fleece, etc.
