Abstract:
Improvements in an expanding arrowhead where the initial launching thrust of launching an arrow keeps the blades retracted within the head of the arrow. The blades remain retracted because the center of mass of the blades is on the opposite side of the rotational pivoting axis of the blades. When the blades contact a target a wing tip on the blades pull the blades open. There are two or three blades that can be retained within the head of the arrow. The blades are loosely retained in a retracted orientation for transportation. The retention is sufficient to overcome the forces or gravity yet release with slight force on then ends of the blades. When the arrow is pulled through the wound track the blades fold back into the head or body.

Claim (Index 1):
An over center expanding arrowhead comprising:\n a body having a slot passing through said body; said body having a central axis; a pivot passing through said body and said pivot retains at least two blades; each of said at least two blades having a centroid of mass; each of said blades have a sharp side located a first elongated side of said centroid of mass; each of said at least blades have a tip that extends out of said body and exist on a second elongated side of said centroid of mass from said central pivot axis, and forces on said tip towards said pivot rotates said blade whereby said sharp side passes through said body to an open orientation.
