|Q.||Does the 20nk chain get sharpened flat (level), or with your hand down 5 or 10 degrees like most chisel chain? I know the 20nk is semi-chisel. I just filed mine, kept my hand flat, but it's not cutting as well as I'd like.|
|A.||You are correct to hold the file flat (no angle). If you are using a 3/16" file only about 20% - 25% of the file should be above the tooth. If any more than that is above the tooth you'll get a blunt edge. If more than 1/3 of the chain has been used, the depth gauges may need to be taken down.|
