Does owning a cool dagger mean I'm required to start my own cult?

So my grandmother gave me this when I was younger and, as any overly protective mother would do, it was immediately hidden away in a box out of a well justified fear my brothers and I would stab each other with it. It's been years now though and I recently found it when cleaning out some stuff and I've developed a greater appreciation for the gift as an adult than I did as a kid. I definitely want to have it cleaned, maybe get a chain for the rings, and find a nice way to display it because it really is a great gift.

Problem is, I have no clue what the cultural significance of it is and would really like to know. My grandfather unfortunately passed away and my grandmother suffers from Alzheimer's so any sort of answer from them is gone now. I believe it's made of bronze, either that or copper I honestly wouldn't know the difference and we're from Venezuela, but my grandfather loved history and kept a lot of objects from other countries so it could be from an ancient Martian civilization for all I know.

Figured someone here might know where it's from and if not, well then you get to see a neat dagger. Now if you'll excuse me, I believe I have some goats to sacrifice at a volcano to some old god.
