I don’t think they have a thing to do with your gas grill.
You got this from a “secondary” source, I’m guessing? I have a feeling the seller was cleaning out some of his “grill stuff” (God knows I never do!!) and they ended up with the Weber.
They do look like something quite important to something though.
So, there’s one mans opinion, surely someone will have a batter idea than I.
I just googled the company, looks like they make a bunch of tools but, I don’t see what that might be part of!
They did show a hassleback potato guide that seems like a good enough idea but, I think I like the old fashioned cake fork, it’s a little less a unitasker.
