<div dir="ltr">Dear YouYue,<div> It looks to me as if there are several active edges on these very interesting tools. Some of the edges look like scrapers while the denticulated edge could be used for leather scraping, beating down the weft in weaving or even pottery decoration and probably ten other activities we can't even imagine. There is no escaping careful study if the surface at high magnifications paired with experimentation to get at the answer for this kind of question. I am curious what other people think though.</div>
