ABSTRACT:
An arrowhead extractor includes an elongated threaded rod having a threaded axial bore in one end thereof adapted for connection to the threaded shank of an embedded arrowhead. A sleeve is then disposed over the rod and a wing nut is screwed onto the rod into engagement with the end of the sleeve. Rotation of the wing nut provides relative movement between the rod and sleeve and an axial withdrawal of the embedded arrowhead.
