Abstract

Removably attachable arrowhead tips that are selectively alignable in specific orientation with structures of their corresponding arrowhead bodies. Such arrowhead tips allow consistent and repetitive alignment of cutting edges of arrowhead tip facet junctures with the cutting edges of tip blades and/or the cutting edges of their corresponding arrowhead blades at all times, such as when replacing a damaged tip.
