A waterfowl luring system provides directional motion to one or more waterfowl decoys. In the diffusion sheet, the first reflection areas and the fourth reflection areas are opposed to each other, and the second reflection areas and the third reflection areas are opposed to each other. The strength of the shaft, which receives the load of the body portion, is secured and at the same time it is possible to achieve miniaturization and weight securement of the body portion. The planning template is positioned in a superimposed orientation with a curvilinear surface of an exposed prosthesis-receiving bone. The via is then plated with metal to substantially close the smaller hole. An anvil extends out in front of the barrel portion and is adapted to receive a removable brush, the needle being aligned to selectively project into the brush.
