Broadhead Arrowhead With Two-Stage Expansion

摘要

Improvements in a broadhead arrow is disclosed where the arrowhead opens in two stages. This provides a broadhead arrow that can be launched with a traditional or compound bow to allow a hunter to bring down large game in an efficient manner. When an arrow is launched the arrow receives a thrust of energy from the string that launches the arrow. The initial thrust partially opens the arrowhead in a first stage of opening to provide a low fight profile that reduces flight air resistance. Regardless of how hard the initial thrust imparted onto the back of the arrow the blades will not open. Because the initial forward launch has no effect on the final opening of the arrow, only minimal impact forces are needed to completely open the broadhead arrow. The broadhead arrow optionally includes at least one side blade that operate with the main blade.
