In its glory days the old Sachs-Dolmar would make short work out of any kind of a woodcutting project. As long as I kept the chain sharp. My brother Lyle told me of going on a firewood gathering project with some fellows from his church. After the first hour or so, the party changed from cutting wood and bragging on the merits of the various brands of chainsaws to a group participation act of trying to help one another make any chainsaw present cut wood.
