Abstract
A cut-on-contact broadhead having a plurality of deployable blades rotatably coupled to a surface of a ferrule, and a plurality of channels disposed on the surface of the ferrule. At least a portion of each channel is defined at least in part by at least a portion of the ferrule and at least a portion of at least one of the plurality of blades. Each blade includes a tip, an impact shoulder, and a first and second cutting edges. During flight, the blades are in a fully retracted configuration forming a distal tip having sharp cutting edges defined at least in part by the first cutting edges of the blades. Upon impact, the distal tip initiates a bore in the target, the plurality of blades deploy into a swept-back configuration, and the second cutting edges expand and lengthen the bore initiated by the distal tip.
