Abstract
A blade-opening arrowhead with a plurality of removable blades, each pivotally connected at one opposing blade end to an arrowhead body by a hinge pin. An urging force produced from a bias element engages the edge of each blade to a holding element to securely hold the blades selectively adjacent to the arrowhead body when in a retracted position. When the arrowhead penetrates an object the blade edges are disengaged from the holding elements, and the blades freely rotate to an open position with the other opposing blade end of each blade rotating away from the arrowhead body. The urging force continually urges the cutting edges of the blades in a forward direction when the blades are in the open position, further slicing uncut or unpenetrated tissue.
