  • Patent number: 4772029
    Abstract: An arrow includes a relatively long shaft, with a front shaft portion adjacent to an arrowhead, and the front portion is designed to collapse upon impact so that the rear part of the shaft, the relatively long portion, is reusable after the collapsed, front portion, is removed from the rear portion of the arrow. The two arrow portions are appropriately secured together, but the securing together is not "permanent". Rather, the securing is of such a nature that the two portions may be separated, with the collapsed portion discarded. The rear portion, the relatively long portion, may be reused by remating it to another front, collapsible portion.
