Researchers into stoneworking methods do examine extant flint arrowheads, and the locations in which they were made, and then test knapping procedures for themselves to find out what gives results consistent with the evidence.&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

Also, though there were indeed copper arrowheads in subsequent pre-history, there is no sign that he even tried to match and recreate what he is doing now against what evidence suggests actually directly superseded the use of flint.&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
