Product was damaged on arrival. This product is not the same product you see in the pictures.
It works as a complete sharpening chain device for both sides and for the top rakes and the cutters. The sharpener files both the cutting tooth and the depth gauge (raker) simultaneously.
This product is listed as a stihl 2 in 1 easy file but buyer beware - this is a cheap imitation of the stihl product. I'm angry that i wasted so much time sharpening and having the saw cut so poorly.
This sharpener is a china made cheap knock-off. It was colored the same as stihl brand ones but did not have stihl molded into it.
