Patent Images
1. An expandable broadhead comprising:
- a broadhead body comprising a longitudinal axis and at least one blade recess;
a tip blade releasably attached to the broadhead body;
a plurality of rear deploying blades residing at least in part in the at least one blade recess and slidingly engaged with the broadhead body, the blades each comprising a cutting edge exterior from the broadhead body when in a retracted configuration, and a camming surface effecting a camming action during deployment of the blades from the retracted configuration to a deployed configuration; and
a shock-absorbing retainer releasably engaged with at least one feature on the rear deploying blades to retain the rear deploying blades in the retracted configuration, the retainer positioned to engage with the rear deploying blade in the deployed configuration, wherein the retainer comprises one of elastically deformable or plastically deformable.

Abstract
An improved expandable broadhead with rear deploying blades. The rear deploying blades deploy reliably upon impact of the blades with a target. The expandable broadhead resists deflection by the target regardless of the angle of entry. Consequently, the present expandable broadhead maximizes kinetic energy on impact and increases the probability of substantial penetration into the target.
