Abstract
Abstract An arrow for hunting includes a razor-type arrowhead comprising two crossed blades removably insertable within a pair of crossed slots in the forward portion of either a tubular or solid shaft. The forward point of the shaft itself is formed with a reduced diameter threaded tip communicating at its rear with a larger diameter stop shoulder. With the arrowhead fully seated within the shaft slots, a forward shoulder thereon is substantially flush with the shaft stop shoulder such that the subsequent application of an internally threaded point member to the shaft tip, secures the arrowhead against both radial and axial displacement relative the shaft.
