The inventive device includes a handle with a head end coupled to the handle. The head end has a first and second faces, and inner and outer side surfaces. The inner side surface of the head end defines an opening through the head end between the first and second faces of the head end. The head end also has a supporting flange extending radially inwards around the inner side surface of the head end. The head end has a break therethrough extending between the inner and outer side surfaces of the head end. The break also extends through an adjacent portion of the supporting flange.
