An overshaft hunting broadhead is used to duplicate practice arrow balance point and flight characteristics. Assuming the optimal balance point of the practice arrow is in accord with manufacturer's recommendations, removal of the practice arrow point and converting to an overshaft hunting broadhead will duplicate the balance point, weight and flight characteristics of the arrow the archer has become accustomed to while practicing. The arrow shaft enters the ferrule of the overshaft hunting broadhead. The ferrule is free to rotate about the axis of the arrow's shaft to be properly positioned, then securely tightened by rotating the arrow tip. The ferrule is equipped to hold cutting edges (razors). The ferrule is coupled securely to the end of the arrow shaft by a hunting point tip that couples into a standard threaded insert in the arrow shaft. The broad head ferrule will not experience the load at impact that is typical to existing broad head styles due to the reinforcement of the arrow shaft by an arrow shaft insert located concentrically and internally beneath the overshaft broadhead ferrule.
In an arrow having an arrow shaft with a threaded insert at a first end thereof, said insert being internal to and concentric with said shaft, and an arrow tip, having a threaded extension, thread coupled to said insert, the improvement comprising:
