There was a Browning and I believe a Shakespere. I remember one of the guys had them and sort of got them sharper with a file. They whistled funny, but they flew straight. He shot a fork horn deer with one and got about four inches of penetration, I helped him find the deer. The next year, he got zero penetration and could not even find a blood trail. So he went to those copperheads with snaggy talon edge, he did not get much penetration with those either. I could not afford that expensive stuff, so I was forced to shoot through deer with Deadheads and Herters broadheads. What gets me, back then there were a number of guys that thought that shooting completely through a deer was not a good thing.
