It is the extra hand you need to
help separate chain-pieced units when quilting. To safely cut the
threads between the chain-pieced units, simply hold the fabric pieces
with both hands and slip the thread into the slot on the top of the
Chain-Piece Cutting 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.
