ABSTRACT:
An extractor for arrowheads including a fork in a generally C-shaped configuration having two spaced parallel prongs with forwardly extending ends and with a base coupling the prongs in spaced relationship. The base is formed with a central first aperture parallel with and intermediate the prongs and with a transverse threaded second aperture coupling the primary aperture with one side face. A threaded set screw is located within the threaded aperture of the base and extends through the first aperture of the base. A handle has a bore there through. A rearward sleeve is positioned within the bore of the handle and has a central threaded bore there through. An elongated threaded rod extends through the forward sleeve and the rearward sleeve and is threadedly coupled thereto. The threaded rod is formed with a forward end located between the prongs with a threaded recess therein for threaded coupling and uncoupling with respect to a threaded portion of an arrowhead to be extracted.
