Abstract
A mechanical broadhead including rearwardly deploying and/or sliding blades. The broadhead includes a ferrule defining a bore joined with a penetrating tip. A connector body, such as a carriage element or a pin, is slidably and moveably disposed within the bore, distal from the tip. One or more cutting blades is joined with the connector body. The connector body moves together in unison with the cutting blades as they expand from a retracted, in flight mode to a deployed, target penetrating mode. The connector body and blades can be joined with the ferrule so that the broadhead converts from a deployed mode to an unbarbed mode to facilitate broadhead removal. Optionally, the broadhead can include an internal retainer element that is resilient and durable enough to be used for multiple deployments. A related method of operating the broadhead also is provided.
