Years ago I had a log cabin built. The logs were about 6" thick and 8" wide. The local sawmill debarked the curved outside section and cut the part that went inside so that the interior would be a flat surface. When the sawmill got too busy they stopped doing the debarking so the contractor did it. He used a draw knife. That's a tool with a blade that is about 1 1/2" by 10" and has handles at each end. You angle it properly to the log and drag it along to remove the bark. If you angle it in too much, it also removes some wood and greatly increases the work. If you angle it out too much you will leave some bark on the log. So, you have to pay a lot of attention and work carefully.
