Buzzblade RN8

Overview
"Mechanics haven't neglected attention for chainsaws by any means-- the selection of newly-crafted weapons also includes the Buzzblade RN8, a chainsaw that eliminates several of the weaknesses found in pre-existing chainsaws. This chainsaw's primary difference from its predecessors lies in the design of its chain-- the teeth of the Buzzblade have a design similar to that of a circular saw, being slanted and sharpened to fine points, in order to slice through infected much more effectively than would be possible with a conventional chain. There has been some confusion regarding the purpose of the short blade affixed underneath the engine housing of this chainsaw, but mechanics involved in its development have hinted that it works as a pivoting flint, allowing survivors to hone the teeth on the chain when they begin to dull from extensive use."
