Bear Broadhead Help insert?

[Shane Reed]

I received this either broadhead without a ferrule or insert shown in middle of picture. This came with a 1956 and some inserts with holes. Any help identifying what this blade in the middle is would be appreciated. It's the same size as a razorhead, but the inner shape is a bit different say if you lay it on a razorhead.

Not sure, but it looks like the main blade from a broadhead I have seen in the past.

I am sure that Johnny Razorhead will have a definitive answer for you.
