Abstract
Embodiments herein provide a cutter link having an end of life indicator to provide feedback to the user that the saw chain, and more specifically the cutter link(s), has been worn and/or sharpened to an undesirable state or degree. There is provided one or more disruptions to the cutting surface of a cutter link in a region that is past the manufacturer's recommended wear limit. When exposed, such disruptions in the cutting surface provide perceptible indications to the user that the chain should no longer be used.
