Abstract

An arrowhead includes a body having a longitudinal axis, a pair of moveable first blades coupled to the body, a second blade having a tip and a rear portion opposite the tip, and a second fastener that engages the rear portion and fixedly couples the second blade to the body.

Claims

exact text as granted — not AI-modified
1 . An arrowhead comprising:
 a body having a longitudinal axis;   a pair of moveable first blades coupled to the body;   a second blade having a tip and a rear portion opposite the tip; and   a second fastener that engages the rear portion and fixedly couples the second blade to the body.   
   
   
       2 . The arrowhead of  claim 1 , wherein the rear portion comprises an extending portion having a tab that defines a first recess. 
   
   
       3 . The arrowhead of  claim 2 , wherein the second fastener comprises a second recess configured to receive the tab. 
   
   
       4 . The arrowhead of  claim 1 , wherein the second fastener is configured to be rotated about the longitudinal axis. 
   
   
       5 . The arrowhead of  claim 4 , wherein the second fastener is a generally cylindrical member that comprises the second recess. 
   
   
       6 . The arrowhead of  claim 4 , wherein rotating the second fastener tends to pull the second blade toward the body in a direction along the longitudinal axis. 
   
   
       7 . The arrowhead of  claim 1 , wherein the second fastener comprises a plurality of generally cylindrical members. 
   
   
       8 . The arrowhead of  claim 1 , wherein the second blade is a cut-on-contact blade. 
   
   
       9 . The arrowhead of  claim 1 , wherein the pair of moveable blades are configured to be in a retracted position during flight and extend to an extended position upon impact with a target. 
   
   
       10 . The arrowhead of  claim 1 , further comprising:
 a pair of first fasteners that are positioned offset relative to the longitudinal axis and rotatably couple the moveable blades to the body.   
   
   
       11 . The arrowhead of  claim 10 , wherein the body is configured to receive a third blade that is interchangeable with the pair of moveable first blades and is fixably coupleable to the body using the pair of first fasteners. 
   
   
       12 . The arrowhead of  claim 1 , wherein the body is configured to receive a third blade that is interchangeable with the second blade and differs from the first blade in at least one of a size and a weight. 
   
   
       13 . The arrowhead of  claim 1 , wherein the second blade includes a cut-out portion extending from a cutting edge. 
   
   
       14 . A body for an arrowhead, comprising:
 a body portion;   first means for fixedly securing a first fixed blade to the body portion; and   second means for interchangeably fastening a second fixed blade to the body portion in a first configuration and rotatably coupling a pair of expandable blades to the body portion in a second configuration.   
   
   
       15 . The body of  claim 14 , wherein the body has a longitudinal axis, and the second means engage the body in a position offset from the longitudinal axis. 
   
   
       16 . The body of  claim 14 , wherein the first means comprises a generally cylindrical member. 
   
   
       17 . The body of  claim 14 , wherein the first means comprises a plurality of generally cylindrical members. 
   
   
       18 . The body of  claim 14 , wherein the first fixed blade is a cut-on-contact blade. 
   
   
       19 . The body of  claim 14 , wherein at least one of the first fixed blade and the second fixed blade includes a cutting edge having at least one cut-out portion. 
   
   
       20 . A method of configuring an arrowhead comprising:
 providing a body portion, a pair of first fasteners, and a second fastener;   coupling a pair of moveable blades to the body portion with the pair of first fasteners;   coupling a first fixed blade to the body portion with the second fasteners;   removing the pair of moveable blades from the body portion; and   coupling a second fixed blade to the body portion.   
   
   
       21 . The method of  claim 20 , wherein coupling the second fixed blade to the body portion comprises securing the second fixed blade between the first fixed blade and the body portion. 
   
   
       22 . The method of  claim 21 , further comprising coupling the first fixed blade to the body portion with the pair of first fasteners.
