Cut precise lengths in fabric and other materials every time. These scissors have a set screw to adjust the length of your cut. Tighten the screw to stop the handle from closing all the way for shorter cuts; loosen the screw for longer cuts. Originally designed to cut buttonholes through fabric, a square notch in the blade makes it so you can start your cut 1/2" from the edge of flexible materials. The blades and handle are made of stainless steel, which resists corrosion from water and mild chemicals.
