such as for snap fit or blade unit biasing elements grip portion 24 forms the body portion 44 of handle 12 by filling channel 26 and at least partially enclosing exterior 45 of core portion 22 grip portion 24 may form gripping elements to enhance a user 39 s shaving experience such as bands 46 or other elements such as bumps ridges ribs and fins for example body portion 44 should be wide enough to be comfortably held by a range of adult hands in one example body portion 44 has a width w of about 0 65 inches while in other examples the width w may be about 0 40 0 45 0 50 0 55 0 60 0 70 0 75 or 0 80 inches those skilled in the art will understand that plastic parts with thick cross sections take longer to mold and require larger molding presses to manufacture increasing the cost of such parts referring to fig2 and 5 core member 48 is disposed in channel 26 thereby reducing the cross sectional area thereof into which grip portion 24 will be formed adding core member 48 improves manufacturability by decreasing molding cycle times of grip portion 24 as will be understood by those skilled in the art in one example the thickness t of wall 50 is about.
