ARROWHEAD HAVING BOTH FIXED AND MECHANICALLY EXPANDABLE BLADES
First Claim
1. An arrowhead for securement to one end of an arrow, comprising:
- a support body having a base and a tip, the tip being opposite the base and having a conical shape;
at least one fixed blade attached to said support body and which includes a base portion for placement within a center slot of said support body, the base portion of said fixed blade being substantially continuous and uninterrupted, said fixed blade being wider than said support body;
at least four expandable blades which are pivotally attached to the support body, said expandable blades having cutting edges formed on leading edges thereof, each of the expandable blades comprising a first end having a hole formed therein for attaching to said support body, and a second end opposite said first end with a spur formed thereon for extending outwardly from said support body when said expandable blades are in a closed configuration thereof, andwherein said expandable blades are pivotally movable between a first retracted position, in which said cutting edges are disposed in slots of said support body, and a second open position in which said expandable blades extend outwardly from said support body with said cutting edges exposed.

Abstract
An improved arrowhead features two sets of expandable blades. The expandable blades are pivotally movable from a first, concealed position to a second expanded position when spurs on the front of the blades contact a target. The first concealed position of the blades allows the arrowhead to penetrate the target upon contact. The fixed blades may be diamond-shaped, double-edged replaceable blades. The expandable blades comprise at least two pivotable blades that can be held in the first safe position by an elastic band. The spurs are located at a first end of the expandable blades, and these spurs are located proximate the base of the fixed blade portion of the arrow head, to allow the fixed portion to penetrate the target before the expandable blades are deployed by the spurs contacting the target.
