After two weeks I am still getting the hang of using the 2 in one guide. It is easy enough to file the correct angle, it works like any file guide. I am working on fairly new chains; so the depth gauges don't need much attention. It is a great concept. The Archer from SawSupplier was significantly less expensive than the Stihl from my local dealer.
Working great
