<p>[QUOTE=&quot;Hommer, post: 2909925, member: 73266&quot;]As was brought up in another thread, a bur on metal is left from improper cutting, period. Even the article you posted tells you this. And also as was brought up in the other thread, when it goes through the upsetting mill, it folds the excess metal over. There isn&#039;t a &quot;bur&quot; there anymore, just folded over metal, hence the name fold over error.[/QUOTE]</p><p><br /></p>
