ABSTRACT:
A replaceable blade cartridge shaving system having an elongate handle with a coupling head formed at its terminal end. The coupling head is arrayed transversely of the handle axis and has two elongate substantially parallel coupling flanges formed thereon. The flanges extend transversely of the head and perpendicular thereto. Located between the flanges and extending a predetermined distance from the terminal end of the handle above a plane containing the flanges is a protuberance member. The cartridge has complementary grooves formed along its base for slidable engagement with the handle flanges and a recess is formed between the grooves having sufficient clearance as to allow the protuberance member to fit therein. Attempted use of the handle with other than a cartridge having such recess produces interference between the handle and the cartridge, thereby preventing slidable engagement therebetween.
