A broadhead arrow head is disclosed with one or more replaceable cutting blades each radially and longitudinally secured in a longitudinal slot of the broadhead body. Each blade has a mounting opening with an inside edge and a stepped trailing edge, and the blade itself is longitudinally movable in its slot between a mounting position, wherein the inside edge of the opening is located below a locking ring extending about the body in a relaxed condition, and a lock position wherein the stepped trailing edge underlies the locking ring to stress the locking ring and effect a radially inwardly directed force on the blade for securing it in position on the body of the arrow head.
