Abstract
An arrowhead of the expandable or mechanical broadhead type, i.e., having blades which unfold to increase the effective cutting area of the arrowhead, includes a tip with a rearwardly-extending actuating member which triggers one or more blades into an open state when the tip strikes a target game animal. The blades are pivotable with respect to a body into which the actuating member extends, and they include ears against which the actuating member presses upon tip impact to trigger the blades open. A latching spring maintains the blades in a closed state until the tip and actuating member are driven rearwardly by tip impact, and the tip and actuating member are preferably maintained in a forward and ready-to-trigger state by an opening spring. The actuating member may extend between the blade ears after the blades are triggered open to fix the blades in the open state until the tip is pulled forwardly to withdraw the actuating member from the ears.
