Novices vs. experienced knappers<br />

<br />

ing, there are substantial differences in performance between those who have<br />

any experience and those with no experience whatsoever. Novice knappers<br />

were able to reduce their cores much less extensively than were experienced<br />

<br />

<br />

<br />

<br />

<br />

at utilizing the surface area of the core.<br />

It is interesting to note that novices produced cores that are statistically<br />

similar to those produced by experienced knappers for a number of linear<br />

dimensions and shape ratios; the cobbles they chose are also similar in terms<br />

<br />

similarities can be partially explained by the pooling of intermediates with<br />

advanced knappers, while shape similarities are expected given the nature<br />
