What is disclosed is a new type of method and device for sharpening the saw chain of a chain saw. In the first stage of the method, a rotating sharpener is brought against the first cutter to be sharpened of the chain and the sharpener is pressed against the first cutter at a set sharpening angle in order to remove material from the cutting edge of the first cutter. The chain is then moved in its longitudinal direction to position the second cutter for sharpening. In the second stage, the rotating sharpener is kept rotating in the same direction as in the first stage and the rotating sharpener is brought at a set sharpening angle against the second cutter to be sharpened in order to remove material from the cutting edge of the second cutter.
