Chainsaw Repair

As with any cutting edge, the more refined it is the longer it will tend to stay sharp. Think of it this way; say you have a sheet of 10 gauge steel and you want to bend the edge of one whole side 180°. Trying to do the whole edge (with hand tools) would be impossible, but if there was a cut every two inches it would be doable. If you look at a cutting edge with a microscope, its nothing like you'd think. Its more serrated. The more rough an edge is, the faster things will act on it. The more refined, the longer it will last cause it acts more like one continuous edge. With chains, I don't know if the time put in is worth the end result.
