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.
