You need the STIHL saw set to restrict the teeth of a chisel tooth saw blade, for example the STIHL chisel tooth circular saw blade, which means turning alternately left and right. By setting the teeth of the saw blade, the saw cut is widened and the circular saw blade cuts through the wood more easily.
This STIHL accessory for cutting attachments is also an indispensable aid when sharpening teeth: The saw set allows you to grasp the teeth, (re)bend them and avoid the risk of injury while working. For your own protection, never bend or sharpen saw blade teeth without using a saw set. The material is made of high-strength steel and will give you many years of good results when it comes to regular and professional maintenance of the cutting tool.
