Expandable arrow broadhead with two-piece folding cutting blades

An arrow broadhead adapted for attaching to an open end of a hollow arrow shaft, the broadhead adapted for moving from a retracted position during arrow flight to an extended position when contacting a target, the broadhead comprising:

• a sliding shaft having a pointed tip, said pointed tip disposed in a front portion of said shaft, said pointed tip tapered rearwardly and outwardly forming a tip base;
• a sliding shaft housing having a bore hole therein and a lower end, said sliding shaft housing receiving said sliding shaft therein, a lower end portion of said sliding shaft received in said bore hole, the lower end of said sliding shaft housing adapted for receipt inside the open end of the hollow arrow shaft;
• a pair of two-piece, folding cutting blades, said cutting blades including a front cutting blade with an outer cutting edge, said front cutting blade pivotally attached to said tip base and to a rear pivot arm, said rear pivot arm pivotally attached to a side of said sliding shaft housing;
• and
• a blade retaining band releaseably attached to said cutting blades for holding said blades in a retracted position during arrow flight;
• whereby, when said pointed tip contacts a target, said sliding shaft moves rearward in said bore hole and said folding cutting blades are pivoted outwardly from said sliding shaft housing into an extended position.
