ABSTRACT:
An aerodynamically and structurally superior, fixed-blade hunting arrowhead providing higher penetration coupled with a structurally sound, non-deflecting, blade-cutting area to take down wild game quickly and humanely. The assembly includes the ferrule, main blade, and sub-blade, wherein the unitary ferrule has a machined structure that holds and reinforces the blade units as well as incorporates a concave-faceted cutting tip, blade-location channels, cavities for blade snap retention, and rearmost threaded portion for attachment to a standard arrow insert. The main blade is a one-piece element which incorporates two forward-cutting blades and two rear blades, as well as rearmost anchoring projections attaching the blade to the ferrule. The sub-blade is a one-piece element positioned perpendicular to the main blade and is retained in the same manner as the main blade by integrated projections snapping into cavities within the ferrule.
