7/32 files for 3/8 chain. The chain we use on 372-288 Huskys (chisel) that is made by Oregon or Stihl has the angle line on the top of the cutter. Never had that untill a few years ago. I like to change the side angle to greater degree after I already have the top angle done by dropping down the hand that has the file handle. This puts a hook in the tooth when you look down on it. Hook in the top and in the side, rakers at about 30thou, cuts great. I only use this for falling, cause if you hit dirt, a rock etc. it takes a while to get an decent edge back. I don't think you can fool around like that with a guide.
