Uh, what about 'em, indeed?
You must be talking about bones used as tools, yes, not just the fact that once a being is buried, what remains after a few decades, is, uh, just bones?
Yes, of course you must.
Well, yes, if you mean a bone that was fashioned and honed to a point to be used as a needle, then, yes, it was produced by tools.
If you mean just a bone that was found and then broken to make an edge, and then used as a knife, yes, that required a tool- a being's hand and arms to break it. The 'use' of the tool is what is in question here. A broken bone located in a burial cistern is not a tool until it is used. But a hammer is, just sitting there.
"Only the usage of a tool can produce an artifact" meets all the truth tests, and is tautological to boot, for what is the definition of 'artifact'?
