ABSTRACT:
An expandable arrow broadhead used for releasable attachment to one end of a hollow arrow shaft. The arrow broadhead includes a pair of two-piece, folding cutting blades pivotally attached to a side of sliding shaft housing and a tip base. The tip base is part of a sliding shaft received in a collar bore in the sliding shaft housing. The cutting blades include a front cutting blade pinned to a rear pivot arm. The front cutting blade includes an outer cutting edge and an inner edge. The cutting blades are held in a retracted position during arrow flight using a flexible band received around a portion of the cutting blades or a coil spring received around the sliding shaft and mounted in the collar bore. Upon target contact, the folding cutting blades are extended outwardly from the side of the sliding shaft housing for increased penetration in the target.
