This special blade pulls the fabric into the scissors rather than pushing it away like traditional scissors. Things you will like about these scissors are the cushioned handle, easy for right or left handed users, blades are sharp to the very tip, serrated blade keeps fabric from fraying, light weight and comfortable. The 7-1/2" size are great for cutting single or multiple layers of fabric. If your quilt has a lot of one shape, layer cutting saves a tremendous amount of time. *Product cannot to be sold on any 3rd Party site such as Amazon, Etsy, Ebay or any other 3rd Party sites.*
