Unearth this wierd thing at a thrift Store

[not2sharp]

I found this thing at a local thrift store and figured it odd enough to make a worthwhile conversation piece. What struck me when I first saw it, that this was clearly too crude for any Western flea market. It looks more like the work of someone who put an extrodinary amount of effort into making it without the benefit of the smallest morsel of talent, or skill, or tools. None-the-less, it has some character:
1) The brass is weakly magnetic
2) it has a vaguely kastane-like handle, but with the blade curving in the wrong direction
3) What is that star and ring/sickle motife?
4) The blade apppears to have broken and repaired.

The whole is very rough throughout; there is no edge or bevel of any kind. If it were some kind of tacky wall hanging, why would there be a sheath? If intended for the performing arts it would have been a painful 2-1/2 lbs lump of metal.

Has anyone seen anything like this before?

BTW, the OAL = 32 inches
