Abstract
A modular broadhead having a blade carrying body, a unitary blade unit with multiple blades each with razor edges extending radially from the front of the unitary blade unit rearwardly to a base, and a locking collar for securing the unitary blade unit to the blade carrying body. The base of each blade extends inwardly toward the central axis of the unitary blade unit and forms a tab capable of being slidably received in a rear slot on the blade carrying body. The blade carrying body has multiple rear slots to receive each tab. The blade carrying body has multiple front slots for slidably receiving each of the blades toward the front of the unitary blade unit. The blade carrying body has outer threads forward of the rear slots. The locking collar has inner threads capable of mating with the outer threads on the blade carrying body.
