<p>A device including a bar shaped housing (11) and a lid (12) as the main body; a double tiered protrusion (13) on the front edge of the lid; a stuck out shaft (14) attached to the end of the protrusion; a trough (15) on the front edge of the housing; an indented cutting set (16) installed in the trough. The hollow portion of the bar shaped housing is for the installation of the wrap film (20). With this device the film will be cut by the length needed through an easy and quick pushing motion onto the lid. This way can save time and energy and meanwhile, keep the film in tidy shape. <IMAGE></p>
