Abstract: The present invention concerns articulated flippers for hands and feet, with a variable surface during swimming, for use by an amateur or a professional, as well as for subaqueous swimmers. These flippers can be used for different swimming styles, such as crawl, swimming on one side, etc. Shoes of various types which are to be put on the feet, and gloves or mitts which are to be put on hands, are used with ribs connected in a hand articulated-joint connection to the shoes and prolongations provided on four fingers of the gloves. The ribs, connected in articulated-joint connection to the shoes or wooden-shoes, and the prolongations for the fingers, support a cartilagineous surface which can open and close during swimming, thus allowing a variation of the friction surface with the water.

Abstract: A bird is gripped by its thighs adjacent the vent hole and is shifted toward a knife until the hole has reached a predetermined location that corresponds to a certain depth of insertion of the knife into the hole. Since location of the hole is being used as the determining factor with respect to depth of knife insertion, the knife always enters to the same extent regardless of the length of the bird. Operation of the knife once fully inserted causes the skin to be slit between the hole and the keel bone, thus making an enlarged opening to the body cavity.
