Well, in all honesty, it's a little amusing to see folks in "shock and awe" over what has been done for literally thousands of years. There is nothing fantastic or magical about new broadheads and what they will do. There are only people who never saw it before.
All of these new broadheads are very good heads, as are all of the broadheads that have stood the test of time. But as a rule, and as a matter of fact, most are ignorant of what has went before, so they are easily awed by photos.
In Duncansville, Pa., near Altoona, there is an antique depot that has a display of a small arrowhead of stone, imbedded in a very big vertebrae....also intact and into the spinal cavity. History is there....we just don't bother looking for it. Everthing is new if you don't know what's old.
