Abstract
An articulated saw chain having pivotally interconnected center drive links and side links. The side links having bottom edges that incur splaying as a result of the side links pounding the guide bar rail during cutting action. An inset portion provided on the center links in the area of overlap defined by the bottom edge surface being pivoted relative to the center drive links. The insets thus providing added clearance to permit substantial splaying of the bar engaging bottom edge surface of the side links without interference and binding.
