Abstract
A broadhead (10) has deployable cutting blades (24 and 26) which are cammed open from slots (20 and 22) in a cylindrical body (14) as plunger (12) impacts against a game animal. The cutting blades (24 and 26) are connected by pivot pins (32 and 34) to the plunger (12). The cutting blades (24 and 26) are pivotable when the broadhead (10) is in an open position from the open, cutting configuration which causes maximum hemorrhaging to a non-barbed configuration which complies with various state gaming laws. A tubular restraint (11) serves to hold the cutting blades (24 and 26) within their respective slots (20 and 22) during the flight of the arrow. The cylindrical body (14) is threadably (60) connected to a cap (28) and the body (14) and cap (28) include matching tapered sections (64 and 66, respectively) which allow for improved sliding of the plunger (12) through the body (14). A pin (44) has been provided as a camming surface for lower blades (26) to improve the manufacturability of the broadhead (10).
