         9 . The arrowhead blade retention device of  claim 1 , wherein the body comprises aluminum and the plurality of lateral walls retain their structure when a cutting force is applied to the retainer outer walls. 
     
     
         10 . The arrowhead blade retention device of  claim 1 , wherein the central body has a thickness between 0.010 inches and 0.150 inches. 
     
     
         11 . The arrowhead blade retention device of  claim 1 , wherein at least one of the plurality of blade retainers has a diameter between 0.050 inches to 0.1 inches. 
     
     
         12 . An arrowhead with deployable blades, comprising:
 a point;   an arrowhead shaft having a first shaft end and a second shaft end, the point coupled to the first shaft end;   a base coupled to the second shaft end, wherein the base comprises a base head and a base shaft;   a blade carrier slidably coupled to the arrowhead shaft;   a plurality of cutting blades pivotally coupled to the blade carrier, the cutting blades comprising blade tips and blade cutting edges; and   a blade retention device, wherein:
 the blade retention device comprises a flexible body comprising a top wall defining a central aperture and at least two blade retainers on opposing sides of the central aperture, 
 the base shaft extends through the central aperture, 
 the top wall is positioned below the base head, and 
 the blade tips align with the at least two blade retainers. 
   
     
     
         13 . The arrowhead of  claim 12 , wherein:
 the base head comprises at least two blade retention apertures,   the blade tips extend through the at least two blade retention apertures, and   the at least two blade retainers align with the at least two blade retention apertures.   
     
     
         14 . The arrowhead of  claim 12 , wherein the at least two blade retainers are recesses defined in the top wall, the recesses comprising recessed surfaces and retainer outer walls, and wherein the blade tips are biased against the recessed surfaces and the blade cutting edges are biased against the retainer outer walls. 
     
     
         15 . The arrowhead of  claim 12 , wherein movement of the blade carrier towards the base pushes the cutting blades in an outward direction away from the arrowhead shaft, breaking the retainer outer walls and releasing the cutting blades from the at least two blade retainers. 
     
     
         16 . The arrowhead of  claim 12 , wherein the flexible body comprises a central body and a plurality of ears that extend upward from the central body; and wherein the at least two blade retainers are defined at least partially within the plurality of ears.
