Abstract
A chainsaw has a saw chain connected so as to be driven by the motor and a guide bar for guiding and supporting the saw chain as it revolves around the periphery of the guide bar. The guide bar has a channel formed by alternatively offset tabs, wherein each tab is offset from its immediate two adjacent tabs such that there is an open segment in the channel opposite each tab. There is a first set of tabs on a first side of the guide bar and a second set of tabs on the opposite side of the guide bar, wherein the alternatively offset tabs keep the cutting chain centered in the channel formed between the first set of tabs and the second set of tabs.
