ABSTRACT:
An arrow which includes a broadhead having a tapered body with axial blade receiving slots formed therein and an axial aperture formed in the rearward end thereof, a point coupled to the forward end of the body, and blades removably received in the slots with their forward ends removably secured in position by the point and with their rearward ends extending rearwardly of the body. The arrow also includes a shaft having a nock at the rearward end therof, an axial aperture formed in the foward end thereof and fletching symmetrically arranged around its periphery adjacent to the nock equal in number to the number of blades. The arrow also includes an assembly coupling the broadhead and shaft. The assembly comprises a cylindrical stem having cylindrical surfaces formed on its forward and rearward ends coupled to the axial apertures in the rearward end of the broadhead and the forward end of the shaft and intermediate external threads therebetween. The assembly also includes a cylindrical cap having internal threads received on the intermediate threads whereby rotation of the cap with respect to the stem will adjust the axial position of the cap along the length of the stem allowing for the varying of the rotational position of the broadhead with respect to the shaft. The assembly yet further includes an adjusting washer positionable for correcting rotational non-symmetry of the arrow.
