Archaeological finds from the Late Bronze Age fortified settlements in eastern Baltic include arrowheads, which are outstanding for their careful finishing. Investigating the making of arrowheads, a certain standardization of arrowheads and uniform manufacturing techniques can be observed. The attention is paid to working traces on these arrowheads; a replica of such arrowhead was also made. An answer is sought to the question whether bone arrowheads were used as weapons or for hunting. Considering the shape and properties of bone arrowheads, as well as the absence or scarceness of arrowheads of other material on these sites, one may conclude that the carefully elaborated bone arrowheads were used for warfare.
