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.

Abstract: A unitary blade unit for an archery broadhead includes a tip structure and at least three blades inseparably connected into a single blade unit. The blade unit requires a separate ferrule in order for the blade unit to be secured to an arrow. Thus, the blade unit can be replaced while retaining a previously used ferrule, or vice versa. In a preferred embodiment, the blade unit is formed by metal injection molding.
