ABSTRACT:
A broadhead arrowhead includes an elongated ferrule to which are removably attachable a plurality of separate blade members. Each blade comprises an enlarged main portion preferably exhibiting a sharpened outer edge, and a longitudinally extending mounting flange portion. The latter is offset from the former by a fixed angular amount and this offset corresponds to the angular disposition between any two adjacent ones of a plurality of radial slots formed in the ferrule. All of the slots communicate with a central, axial passageway within the ferrule and which extends through its tip. Attachment of the blades is accomplished by sliding each blade rearwardly through the ferrule leading end, with the apex of the angularly offset blade portions passing into the ferrule axial passageway as the two blade portions slide into two separate, adjacent ferrule slots. Remaining blades are similarly attached, with the flange portion of one blade being inserted into the same slot as occupied by the main body portion of an adjacent blade. The width of the ferrule slots is formed to insure a close sliding fit when the above portions of two blades are disposed therein. Secure anchorage of the installed blades is achieved as a notch formation at the rear of each blade straddles a mating formation adjacent the rear of the ferrule slots and tangs on the front of the blades are captively retained upon the application of a removable tip member to the leading end of the ferrule.
