After fans requested a medium size of Karen Kay Buckley's Perfect Scissors™, she was happy to comply. One blade is micro-serrated and one is a regular blade which can be sharpened. The micro serrated blade pulls the fabric into the scissors rather than pushing it away like traditional scissors. This keeps fabric from slipping so cutting is more accurate and also helps to prevent frayed edges. As with all Karen Kay Buckley brand scissors, they have a soft grip handle and a plastic protective cover.
