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 fabric smoothly. This special blade pulls the fabric into the scissors rather than pushing it alway like traditional scissors. Things you will like about these scissors: cushioned handle, easy for right or left hander to use, blades sharp to the very tip, serrated blade keeps fabric from fraying, light weight and comfortable. The 4" size are great for detail cutting on curves and points.
