I read the paper. I found no such claim - please cite.
> The authors state in their abstract this is their goal, to push back the evidence of such a "social history", to a time before archeologists made up the narrative about hand-axes. The authors are literally attempting to incept the archeological claim to a prior age of modern history. Is that what you mean, because that is definitely and literally the motive of this research.
They literally do not do so.
They claim that the stones we call handaxes were considered a separate type of rock. Then they discuss various conceptualizations of that rock at the time. They claim that one person thought it was interesting that category of stone including handaxes bore a resemblence to arrowheads from the new world, but his work wasn't published until 1717 (long after that person's death).
You seem mad at archaelogists for claiming things like "these handaxes are old" in general, and specifically at these guys for pointing out historical descriptions of things that sound like handaxes, and paintings that look a lot like handaxes. They literally (using a dictionary definition of the word - in this case the factual definition) state in their paper:
"In the knowledge that works of art are not exact transcripts of reality, it would be difficult, if not impossible, conclusively to identify whether a handaxe is represented in this fifteenth-century painting. We can, however, potentially strengthen the inference that a handaxe is depicted through three artefact-based routes of inquiry."
I'm not sure what you're going on about, your claims seem false upon reading the paper.
