Abstract
An archery broadhead including a ferrule and at least one replaceable blade, each including interlocking features that securely lock at least the forward portion of the blade to the ferrule. The ferrule defines a blade slot bounded by a land and an inclined surface overhanging a portion of the land. The land and inclined surface form a locking pocket. The blade includes a cutting edge and a locking member. When the broadhead is secured to an arrow, the locking member wedges within the locking pocket to secure the forward portion of the blade to the ferrule. A method is provided including: metal injection molding a ferrule to define a locking pocket, sintering the ferrule, and joining a blade including an locking member with the ferrule so that the locking member wedges within the ferrule locking pocket.
