I'm sure that someone will recognise it.
Being the owner of several mystery objects acquired over the years, I'd be interested to know.

I see your point Mel but, i am reluctant to digest that this is a non weapon implement. Not so much a question of common sense but, i would be frustrated to realize that i acquired something i wasn't expecting ... at all.
If ever someone pops up and shows us he is famiiar with this thing as not being a scabbard frame and, once you fancy odd obects, you can have it ... and i mean it. .
