Abstract: 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.

Abstract: An arrow balancing tool is used in establishing the optimal balance point on an arrow to produce the most efficient flight characteristics in accord with manufacturer recommendations. Assuming that the optimal balance point will fall toward the nose end of the arrow, approximately 7 to 10% of the arrow length removed from the midpoint of the arrow, the invention provides a base with a scale graduated in units equivalent to 57% of the length of the arrows being balanced. A second scale is graduated in units representative of 60% of the lengths of the various arrows to be balanced. A reference point, zero on the various scales, is established at which the nock of the arrow is positioned. A fulcrum, slidingly coupled to the tool, is adjusted until the balance point of the arrow is determined. Indices on the sliding fulcrum are positioned for a readout on each of the scales. Actual scale values reflect current manufacturer recommendations for optimal balance of an arrow.
