PUCKETT.1 A broadhead (10) includes a pair of upper blades (24) and a pair of lower blades (26) which are held within slots (20 and 22, respectively) in a cylindrical body (14) while the arrow is in flight. Upon impact with an animal, a plunger tip (12) slides into the cylindrical body (14) and the upper and lower blades (24 and 26, respectively) are forced to their open position by acting against the cam surfaces (38 and 44) positioned within the cylindrical body (4). A C-shaped ring (48) performs the functions of holding the plunger tip (12) in its extended position in flight and locking the blades (24 and 26) in their open position upon impact.
