Abstract
A cut-on-contact broadhead having a ferrule and a plurality of deployable blades pivotally coupled to the ferrule. The ferrule includes a plurality of recesses, and at least one protrusion extending away from a surface of one or more of the plurality of recesses. Each of the plurality of blades includes a tip, an impact region, a first cutting edge, and a second cutting edge. During flight, the blades are in a fully retracted configuration forming a chisel tip having cutting edges defined at least in part by the first cutting edge of each blade. Upon impact, the plurality of blades are deployed into a swept-back configuration whereby the second cutting edges expand the bore initiated by the chisel tip.
