Arrowhead with removable blades

An arrowhead assembly with removable blades for attachment to the forward end of an arrow shaft comprising:

• a body of generally circular cross section having a forward end and a rearward end, a generally pointed nose extending from said forward end and said rearward end having fastening means for securement to said forward end of an arrow shaft, said body having a shoulder portion at the forward end of said fastening means, said body having multiple radial slots along its long axis for receiving said removable blades, said slots terminating in an acute angle stop at their forward end in the region of said nose and extending into said shoulder portion at their rearward end;
• a non-deformable blade locking ring fitting over said shoulder portion of said body, said locking ring having an undercut forward portion spacing the forward portion of said ring outwardly from said shoulder, the rearward end of said undercut forming an acute angle to the axis of said ring;
• a compressible ring fitting over said shoulder of said body adjacent the rearward side of said locking ring and adjacent the forward end of said arrow shaft, said compressible ring being in compressed condition when said arrowhead assembly is installed on said arrow shaft;
• and
• multiple blades having a shape exterior to said arrowhead body adapted for good aerodynamic flight characteristics and deep target penetration, said blades having an acute angle at their forward ends to mate against said acute angle stop and having an extension at their rearward ends to mate within said non-deformable locking ring undercut portion and an acute angled end to mate against said angle at the rearward end of said undercut.
