ABSTRACT:
A broadhead includes a ferrule for mounting an arrowshaft, the ferrule having a locking portion. At least two blades are mounted on the ferrule (three are used in the preferred embodiment), the blades being coupled to the ferrule in their center portions by notches that mate with the locking portion of the ferrule. A locking nut is mounted on a rear portion of the ferrule for holding the three blades in place on the ferrule when the locking nut is tightened.
