The one on the left looks like a knife with the blade to the right side and handle on the left.

Yeah, but think about actually using a rock that thin as a knife. We're not talking galvanized steel here. You could use it for what, one cut? And hope that works before it breaks into pieces?

Obsidian scalpels are used in medicine successfully, they're ridiculously sharp. I'm not a rockalogist to say it would or wouldn't have been useful tho

They're also very delicate. Not to say obsidian isn't/wasn't used for cutting tools, but afaik they were thicker and just knapped on the edge.

Obsidian is a very special rock made under special circumstances. When I hear someone say "made of rock" I think of rocks I would find anywhere and not obsidian.

So yeah rock based knives are useful but if you only include common rock types I imagine they would probably suck or have to be sharpened constantly.

Flint is what's used and it was everywhere. Even made some as a kid when we were bored.

That rock is not obsidian. It doesn't look like flint to me either when I look up images of flint. So, again, looks way too flimsy to be a tool.

It's not like sandstone and granite have the same hardness because they're both rocks.

Assuming it's an actual old tool, my bet would be more scraper than knife. However, taking things out of their archaeological context and stratigraphic placement and/or manufacturing fakes kinda ruins all of the everything.

It's not an old tool.
