Nice haul!
I started with Bear heads in 1970 and mostly stayed with them until they just became almost impossible to find, around 2000 or so.
I loved how easy they were to sharpen, they flew well, and without the bleeder put white-tail, mulies, and pronghorn down in quick order. I'm sure the bleeder was fine but I never liked them much because of the way they fit and I wasn't as good at shapening them.
I recently cleaned out nearly every old one I had and sent to a fellow in Texas for an old Bear Quiver I recall.
I did have a few of the Bear's come apart in critters with the main blade twisting or breaking free from the ferrule. Of course by then the deed was done and the beast was mine.
