My wife says I have a hoarding problem so I brought together most (but not all) of my razorheads. She might be right. Here is the patent doc. They were not patented by Fred Bear. http://www.freepatentsonline.com/2829894.pdf A few 1956 Bubble heads with pin hole bleeders that aren't mounted on arrows. The ones mounted on arrows were too big of a pain to gather for the photo.) I have every vintage except the rare Pinned head. I think I have more bear arrows than broadheads. Time to purge. (So I can buy more)
