Karen Kay Buckley has used nothing but serrated edge scissors to cut her fabric for the past 25 years. She designed these scissors with micro-serrated blades which both holds and cuts threads smoothly -- while the curved shape of the blades keep the tips away from the fabric. This size is great for trimming threads for machine embroidery machine applique and machine quilting. This special blade pulls the threads into the scissors rather than pushing it away like traditional scissors. Things you will like about these scissors: cushioned handle easy for right or left hand use blades sharp to the very tip serrated blade light weight and comfortable.
