Chainsaw chain sharpening marker

A chainsaw sharpening marker system comprising:

• a chainsaw body including a motor, a guide bar, and a drive mechanism configured to rotate a chainsaw chain along a longitudinal axis;
• a chainsaw sharpening marker apparatus, comprising:
• a chainsaw chain mounted to the guide bar and configured to travel along the longitudinal axis, the chainsaw chain including a plurality of cutting teeth, the cutting teeth alternating in orientation between a first angle and a second angle relative to the longitudinal axis;
• a plurality of sharpening markers, each sharpening marker disposed directly on a corresponding cutting tooth of the chainsaw chain;
• wherein each sharpening marker comprises a plurality of aligned marks etched into the surface of the cutting tooth at a predetermined sharpening angle corresponding to the orientation of the tooth;
• wherein the aligned marks are positioned such that a first mark is located proximal to a cutting edge of the tooth and at least one subsequent mark is located distal to the cutting edge along the same angular direction;
• wherein the aligned marks are disposed at consistent angular orientations for similarly-oriented teeth and at alternating angular orientations for alternately-oriented teeth, configured such that a user visually aligns a sharpening tool with the aligned marks during a sharpening operation to maintain a consistent sharpening angle and to monitor material removal across all cutting teeth.
