Abstract
A broadhead having a penetrating, forward tip, a longitudinally extending body with threads on the rear end thereof for attachment to an arrow shaft. The body includes a single longitudinally extending passage or, alternatively, two or more longitudinally extending grooves for receiving blades therein. The blades are provided with a longitudinally extending, weight or mass reducing, slot and are held within their respective passage or grooves with transversely positioned or friction holding members which permit rearward sliding movement, resulting in outward expansion, of the blades while retaining a portion of the blades within the passage or groove. The front end of the blades extends outwardly of the body to contact the target surface and provide a rearward moving force to the blades upon such contact. The slots of the blades are formed to allow the rearward ends thereof to move outwardly to an expanded cutting position as they move relative to the holding member or, alternatively, the blades are directed outwardly by an additional transverse, camming member as they move relative to the holding member.
