Abstract:
1. A blade-opening arrowhead device, comprising: a) an arrowhead body having a blade slot extending longitudinally between a rearward end toward a forward end, the blade slot having a pivot pin hole near the rearward end; b) a blade disposable in the blade slot and having a forward end, an opposing rearward end and a cutting edge extending therebetween, the blade having a corresponding pivot pin hole near the rearward end alignable with the pivot pin hole in the arrowhead body; c) a pivot pin disposable in the pivot pin hole of the arrowhead body and the corresponding pivot pin hole of the blade to rotatably connect the rearward end of the blade to the arrowhead body such that the blade is rotatable between a retracted position with the blade stowed in the blade slot and a deployed position with the forward end of the blade rotated away from the arrowhead body; d) a flexible wedge slot disposed in the arrowhead body and oriented substantially orthogonal to the blade slot; and e) a flexible wedge disposable in the flexible wedge slot and extending into the blade slot to contact and apply a wedging force against the blade when the blade is in the retracted position.
