In recent years there have been some differences of opinion among archaeologists as to the probable use of artifacts shaped like arrowheads but larger than the small so-called “bird points” and ranging in length up to 4 or 5 inches. Some think they are too large and heavy for arrowpoints and must be either knives or spear points. In an attempt to throw some light on this question, tests were made using points varying in weight from that of the smallest “bird points” up to that of spear heads.
