Saw this at a flea market with other kitchen tools and do not know what it is. The end of the tool that is pictured is attached to a wooden handle, not a gear or some other mechanical attachment.
Update: I'm still Google searching periodically. Other ideas include parts for a cookie/pasta press.
This is what the handle looks like:
I think I'm on a lead with these grill scrapers.

I'm fairly confident that the tool is in fact a grill scraper. The handle matches the wooden one shown below. I can't think of any other explanation for the one indent on the tool that is like a hook. You ban see it matches the one in the two metal scrapers. The idea behind the design is to scrape both sides of the grill rung at the same time.
