ABSTRACT:
An extrusion implement includes a pair of generally cylindrical housing portions connected to one another by sets of complementary threads to permit a telescoping of one portion into the other. An open end of the smaller cylindrical portion is partially closed or restricted by one of a plurality of end caps providing various shaped apertures. A viscous material, such as modeling clay, is inserted within the cylindrical portions and a biasing device is provided to constantly urge the viscous material outwardly through the aperture. Relative rotation of the housing portions causes a telescoping effect to regulate the amount of pressure applied by the biasing device. An end cap is pivotally mounted to close the opening when the implement is not in use.
