摘要： A crossbow includes a riser. The crossbow includes a first limb and a second limb. The first limb includes a first end and a second end. The second limb includes a first end and a second end. The first end of the first limb and the first end of the second limb are coupled to the riser. A first wheel is rotatably coupled to the first limb proximate the second end thereof. A second wheel is rotatably coupled to the second limb proximate the second end thereof. The crossbow includes a first power cord that includes a first end coupled to the riser and a second end coupled to the first wheel. The crossbow includes a second power cord a first end coupled to the riser and a second end coupled to the first wheel. The crossbow includes a bowstring. The crossbow includes an efficiency of at least 80%.

摘要： 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.

摘要： 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.

摘要： A crossbow having an energy storage system configured for storing energy when a bowstring is cocked at full-draw and releasing at least a portion of the stored energy when a trigger is pulled releasing the bowstring. The stored energy is defined by an area under a power-curve or draw-curve of the crossbow. The power-curve is defined by the force required to draw the bowstring from an un-cocked position to the cocked position. Between the un-cocked position and an intermediate position, the force required to draw the bowstring is substantially proportional to the draw distance. Between the intermediate position and the cocked position, the force required to draw the bowstring is substantially constant. When the cocked bowstring is released, at least a portion of the stored energy is transferred in the form of kinetic energy of an arrow or bolt nocked on the cocked bowstring.

摘要： A cut-on-contact broadhead having a plurality of deployable blades. Each of the plurality of blades is pivotally coupled to a ferrule configured for attaching the broadhead to a shaft of an arrow or a bolt. Each of the plurality of blades includes a tip, an impact region, a first cutting edge, and a second cutting edge. During flight, blades are in a fully retracted state forming a distal tip of the broadhead having sharp cutting edges defined at least in part by the first cutting edges of the blades. Upon impact, the distal tip of the broadhead creates a bore in the target. As the broadhead penetrates the target, the plurality of blades are deployed into a swept-back configuration exposing the second cutting edge of each blade. The second cutting edges expand the bore initiated by the distal tip of the broadhead and create a passage in the target.
