I'm kind of suspicious that neither the abstract nor the article shows a picture of anything resembling a stone tool. Perhaps the field has been defining random rocks with hammer marks as "stone tools" for excitement, and showing a picture would have made people say "well a monkey could have done THAT" all along?

This is exactly what has happened in many cases.
