Abstract: An arrowhead comprises a conical ferrule having a rounded tip with a slot therein. A primary blade is securely brazed on the outside of the ferrule. The primary blade extends forward well beyond the rounded tip and has an opening in that portion of the blade which projects beyond the rounded tip. A replaceable auxiliary blade fits into the ferrule slot and includes a pair of fastening arms which snap into a pair of holes on the ferrule. The auxiliary blade is positioned perpendicular to the primary blade with its pointed tip located within the primary blade opening.
