blades 72 in the retracted configuration 80 upon impact the penetrating end 54 proceeds into the object as the retractable broadhead 50 advances into the object the impact edges 82 also contact the object because the impact edges 82 extend beyond the perimeter of the broadhead body 52 movement of the expandable broadhead 50 into the object causes generally oppositely directed forces 124 to act on the impact edges 82 in the illustrated embodiment the impact edges 82 are angled slightly backward relative to axis 119 perpendicular to longitudinal axis 120 consequently forces 124 applied to the impact edges 82 generate torque 134 on the blades 72 that assists in releasing the notches 96 from the retainer 86 in an alternate embodiment the impact edges 82 extend perpendicular to the longitudinal axis 120 the forces 124 acting on the impact edges 82 at a distance from the longitudinal axis 120 is sufficient to deploy the blades 72 as best illustrated in fig4 b once the notches 96 are released from the retainer 86 the camming edges 92 ride along the retainer 86 towards the deployed configuration since the widths 110 of the slots 100 in the center region 108 between the first and second ends 102 104 are greater than the diameter of the pivot feature 76 the blades 72 move relatively freely in the free floating region 109 fig4 c is a sectional view of the expandable broadhead 50 in the deployed configuration 130 in accordance with an embodiment of the present invention.
