The Gizmo is the extra hand you always need when separating chain-pieced segments of your quilt tops. It stands steady on your table, allowing you to safely cut chained pieces by holding the fabric with both hands and slipping the chain into the slot on top of the Gizmo. The embedded razor blade cuts the thread quickly, easily and safely. The non-slip bottom ensures that it will stay in place when in use. Five replacement blades and the magnetic tool needed for blade changes are stored in the base.
