Abstract: The present invention is an archer's broadhead having blade elements supported by a mandrel preferably disposed in a longitudinally extending ferrule. The blade can incorporate a flange portion or a loop. The mandrel preferably comprises threaded portions and incorporates a collar, which collar is adjustable along the length of the mandrel. The ferrule defines a longitudinally extending central cavity and a plurality of ferrule slots extending from and communicating with the central cavity. Upon broadhead assembly, the flange portion (or loop) of the blade is located in the ferrule cavity between the outer surface of the mandrel and the inner surface of the ferrule. The arrowhead tip can engage a top section of the mandrel, a top section of the ferrule, or both, to secure the top of the blade elements and mandrel to the ferrule. The broadhead fixedly secures to an arrow shaft at a mounting component.
