摘要： For users of chain saws it is known that the chain saw teeth should rather often be sharpened by filing in order to keep them well cutting. Traditionally, such a sharpening is effected by means of a straight filing rod moved in a reciprocal manner, but according to the invention it is realized that it is better to arrange the rod as a rotary circular or screw shaped formation, whereby the teeth can be worked in a simplified manner.
