When I want to cut a big piece of fabric, this is the scissor I grab.
Karen Kay Buckley has designed a wonderful shear with a micro-serrated blade. The scissor grabs and holds your fabric, keeping it from slipping around as you cut. You will love the way they cut AND the way they fit your hand.
This scissor comes with it's own hard plastic sheath.
