Abstract
The present invention relates generally to a monolithic broadhead including a ferrule and a blade having a tapered cross-section. The ferrule is formed with a threaded portion for attaching the broadhead to an arrow shaft in a conventional manner. Through the use of powdered metallurgy, the blade may be formed of a metal having a high hardness for maintaining edge sharpness and the ferrule may be formed of a high strength material for maintaining the durability of the broadhead.
