It is unlawful to hunt big game animals with
a broadhead blade unless the broadhead
is unbarbed and completely closed at
the back end of the blade or blades by
a smooth, unbroken surface starting at
maximum blade width forming a smooth
line toward the feather end of the shaft and
such line does not angle toward the point.
That is from the Reg's. The Wac'em doesn't have a smooth, unbroken surface. They considered it a barb. If you look at the broadhead it has that little notch by the shaft.
